Driftnet is a program which listens to network traffic and picks out images from TCP streams it observes. Fun to run on a host which sees lots of web traffic. In an experimental enhancement, driftnet now picks out MPEG audio streams from network traffic and tries to play them.
(Obviously, driftnet is an invasion of privacy of a fairly blatant sort. Also, if you are possessed of Victorian sensibilities, and share an unswitched network with others who are not, you should probably not use it. If youre looking for a less dubious network monitoring application, you might want to take a look at Paul Warrens iftop.) You can also now use driftnet with Jamie Zawinskis webcollage, and it can run as a screen saver.
Enhancements:
- Changed the algorithm used to search for image start blocks to Boyer-Moore, for a performance improvement.
- Fixed some build errors.

This pack is our way of saying "Thanks" for purchasing UT2004. We hope you enjoy it!

Three new vehicles:

SPMA (Self Propelled Mobile Artillery)
The SPMA is a two person vehicle, with the driver controlling a long range artillery piece. Alt-fire deploys the spotter camera. Enemies will want to shoot down the spotter camera as soon as they see it, to keep the SPMA from raining destruction from afar. An AVRiL at the spotter camera will automatically re-direct toward the SPMA if it ever becomes visible to the AVRiL.

Paladin
The Paladin is a defense focused vehicle, with a powerful energy projectile cannon and a defensive shield alt-fire. Firing the cannon while the shield is deployed will heavily damage nearby players.

Cicada
The two-man Cicada ground attack bomber is a powerful weapon against ground targets, but is easy prey for Raptors. The pilot can fire missiles, or use the alt-fire to specify a target. While holding alt-fire, multiple missiles are loaded up, and released when alt-fire is released. These missiles will all track toward the specified target location, so the alt-fire can be used to avoid enemy fire while loading up missiles. The second seat in the Cicada is an energy beam turret located on the belly of the Cicada. Its alt-fire is chaff that can be used to confuse incoming AVRiLs.

Six new characters:

Mekkor (Skaarj)
Mekkor is from the Black Fist Clan, sworn enemies of the Iron Skull Clan. Severely injured in battle, he is testing his new cybernetic armor in the Tournament.

Karag (Iron Guard)
