I'm found yet another multiprotocol IM client (Jabber, mail.ru agent, vkontakte, ICQ etc) - MDC.

Client looks good and list of futures is not minimal. Written with QT.

My Fedora 14 rpms placed here. For whom have enabled my hubbitus repository installation simple single command:

yum install mdc

If you need rpm for other Fedora version or architecture - feel free ask into comments.
