I have used Adium for over a year along with others in my policy group as a secondary communication channel during group teleconferences. My primary, and really only, use, therefore, is a group chat at a password-protected jabber conferencing site. I searched and searched the menus of Proteus, but I could not discover how to join a group chat room. I can do it easily with Adium and with Pidgin on my new ASUS Eee PC (Xandros Linux based). So, for me, Proteus is useless, as is Psi, because the latter does not support passworded logging into chat rooms.

Also, when I tried to set up my jabber account with Proteus, I kept failing until finally I noticed that it was necessary to open another tab to enter the host name for my account. I had thought that it was implicit in my account name (user@host).

Bottom line: Adium is still my chat client of choice for MacOS
