Another client to try is Lopster. I am not sure if it works for Linux. The URL is http://lopster.sourceforge.net/. It worked well when I was using FreeBSD.
You might also try TekNap, http://www.teknap.com/. The chat feature works really well and it is very handy for server administration. I never really used it to share files, but I know that you can do so. I hope this helps you out. David
