Are there XMPP conference servers for IETF in use outside of IETF meetin

There are times when I hunger for IETF chat rooms in between IETF
meetings.  Some mailing list discussions suffer from latency + piling
on.  I understand that IM chat rooms would often suffer from lack of
attendance, but a sort of interim meeting could get called on IM much
more often than physical interim meetings, and might help resolve
disagreements / reach consensus more quickly and with less effort than
e-mail (consensus would still have to be confirmed on-list, of
course).
