I’ve found decent unified IM clients on both Mac and Windows - this is a huge and pleasant surprise for me. Over the last few years I’ve tried various programs that claim to work with all of the chat protocols (Yahoo, AIM, MSN, IRC, etc.) but they all sucked badly (Trillian). Finding a program on each platform that doesn’t suck makes me happy. I tried to donate, but I couldn’t find a donation box on either page… I’ll try harder at some point.
Check out Fire for Mac OS X and Gaim for Windows and Linux.

Thanks for the ‘Fire’ link, I’ve been looking for a Trillian-like client for OS X!

Have you tried Proteus? I like the UI better than Fire, but both tend to be slightly buggy. Development on Proteus seems to have slowed down big time.
Also, I’ve heard rumors that iChat 2.0 will support multiple services (crossing fingers and toes - doing rain dance - tossing salt over both shoulders).

I think I tried Proteus a year or more ago, I should give it another shot. Especially since Fire doesn’t seem to like to connect to some of the protocols through a firewall.

Proteus is my best bet for a Mac multi-client now, though it does not support file transfer yet.
A newcomer on the scene is Adium (www.adiumx.com) , which is still in alpha, but from the alpha versions it looks like it’s really going to kick a**
