Meebo may be the application you've been dying to have on Linux. It's an IM client which handles multiple prootocols -- Yahoo!, MSN, GTalk, ICQ, AIM, and Jabber. While that's fewer than Pidgin, it's still a lot. The tasty addition is the support of voice and video chat, which Pidgin lacks. Meebo also has group chat functions, multi-player games, and streaming music videos. Oh, yeah, it's also cross platform. How does it do this? It's a web app, of course.
The voice and video functions require Flash support in your browser, but so much of the web is already Flash that you probably wouldn't notice, right?
The full list of "extras" is:
- Voice / Video chat
- File transfer
- Group voice chat
- Group video chat
- Multicast -- create your own live show
- Transliteration into Hindi, Russian, and Arabic
- Multi-player and single-player games like checkers, chess, sudoku, and pirate wars
- Recent political and entertainment photo feeds
- Sony music videos
