Free business communication software for linux

Libtubo Interprocess Communication is a small and simple library that can run processes in the background and communicate via the stdout, stderr, and stdin file descriptors.
The functionality of libtubo is similar to the glib function g_spawn_async_with_pipes(), except that all pipe setup and monitoring is taken care of.
The calling function only has to provide the functions with which to process the input/output of the remote process.
The library first appeared in the year 2000 in the xfce3 desktop as part of the xfsamba application, and is now available for use for other developers.
Enhancements:
- Some control bugfixes.
- The version has been updated to the xffm scheme, as this package is now distributed with xffm.

Ice, the Internet Communications Engine, is middleware for the practical programmer. A high-performance Internet communications platform, Ice includes a wealth of layered services and plug-ins. Ice means simplicity, speed, and power.
Ice is available under the terms of the GNU General Public License (GPL). Commercial licenses are available for customers who wish to use Ice with proprietary products. Please contact sales@zeroc.com for more information.
Ice is currently available for C++, Java, C#, Visual Basic, Python, and PHP, and is supported on various operating systems. Additional operating systems and languages will be supported in future releases.
Ice consists of the following packages:
Slice The Specification Language for Ice. Slice establishes a contract between clients and servers, and is also used to describe persistent data.
The Slice Compilers Tools to compile from Slice into target languages, such as C++ and Java, or to automatically generate documentation from Slice files.
Ice The Ice core library. Among many other features, the Ice core library manages all the communication tasks using a highly efficient protocol (including protocol compression and support for both TCP and UDP), provides a flexible thread pool for multi-threaded servers, and additional functionality that supports extreme scalability with potentially millions of Ice objects.
IceUtil A collection of utility functions, such as Unicode handling and thread programming. (C++ only.)
IceBox An application server specifically for Ice applications. IceBox can easily run and administer Ice services that are dynamically loaded as a DLL, shared library, or Java class.
IcePack A sophisticated server activation and deployment tool. With IcePack, the complex task of deploying applications in a heterogeneous computer network is dramatically simplified. Simply write a deployment descriptor in industry-standard XML, and IcePack handles the rest.
Freeze Freeze provides automatic persistence for Ice servants. With just a few lines of code, an application can incorporate a highly-scalable evictor that efficiently manages persistent objects.
FreezeScript It is common for persistent data types to change, especially in large software projects. In order to minimize the impact of these changes, FreezeScript provides inspection and migration tools for Freeze databases. The tools support an XML-based scripting capability that is both powerful and easy to use.
IceSSL A dynamic SSL transport plug-in for the Ice core. It provides authentication, encryption, and message integrity, using the industry-standard SSL protocol.
Glacier One of the most difficult challenges for object middleware systems is security and firewalls. Glacier, the firewall solution for Ice, greatly simplifies the deployment of secure applications. Glacier authenticates and filters client requests and allows callbacks to the client in a secure fashion. In combination with IceSSL, Glacier provides a powerful security solution that is both non-intrusive and easy to configure.
IceStorm A messaging service with support for federation. In contrast to most other messaging or event services, IceStorm supports typed events, meaning that broadcasting a message over a federation is as easy as invoking a method on an interface.
IcePatch A patching service for software distributions. Keeping software up-to-date is often a tedious task. IcePatch automates updating of individual files as well as complete directory hierarchies. Only files that have changed are downloaded to the client machine, using efficient compression algorithms.
Enhancements:
- Various additions, including redundant IceGrid registries.

Web Business Pro is a Web application designed for everyday business activities. The project includes support for customer lists, inventory, receipt printing, and accounting. Fully featured search functions and filters make it easy to find what you need quickly.

Kumula is designed to become a complete software suite for business needs. Started as software for consultants, it is flexible enough to be used by almost any class of business. Kumula Business Suite provides a small CRM (Clients) and a Mini-DMS (Documents), enhanced by some other applications. Everybody is invited to use it or enhance it.
Kumula is written in Qt (http://www.trolltech.com/products/qt/), PyQt and Python using the fabulous Eric3 development environment.
Enhancements:
- This is the last stable release before Ill port it to Qt4 (as "Kumula2"), so I feel free to call it "1.0".
- The whole suite is becoming bigger and bigger, so now its time to split it. This is the base package with the central Kumula library and the most important applications. The package contains the following programs:
BizCalc:
- The modular designed calculator tool, coming with a spartanic RPN calculator and an unit conversion module
Clients:
- The client/customer management application, with many improvements (like individual client attributes) and the modules "Info" (logo+description), "Contacts" (for managing contact persones, addresses and communication data) and "Tickets" (for letting the users talk about a client like on a web forum)
Configurator:
- The central configuration utility, to setup the database access and the user interface (menus, icons, ...) of all Kumula applications.
Users:
- A small tool for managing the people using Kumula.
- Further application will be provided in separate packages for easier maintenance and faster bugfixes and updates.

SAP R/3 Communications Suite allows SAP R/3 servers to communicate with external devices such as fax and GSM modems by sending and receiving a fax or SMS.

SAP R/3 Communications Suite provides an easy configuration through a Web interface and a JMX console.
