TriX chat based on the VyQChat (author homepage - http://linux.bydg.org/~yogin/). The project is released under terms of GNU GPLv2 license. As compared to VyQChat in TriX such new features appears as: files transfer, bulletin board, users avatars, logs, links navigation, broadcast and multicast type of connection, search by IP address and many other, not listed here things.
Now TriX is compatible with 2.0 protocol version of the Vypress Chat (TM) developed by VyPRESS Research, but there are some protocol differences in TriX (needs to support avatars).
TriX writed in C++ with Qt library from Trolltech company. Current version of TriX has been tested under Fedora Core 3...6, Fedora 7, 8, Debian GNU/Linux 3.1 Sarge, Slackware Linux 10.1 and others.
For now TriX is supported by few people, so if you have any ideas how to improve the project you can ask for us. Any comments are welcome.
