It would be nice if the GROUP feature on TpChannel implied that each member was available as a TpContact. I have a half-written branch for this; I haven't finished the implementation, let alone tested it, so it might still get rebased.
I've added TP_CHANNEL_FEATURE_CONTACTS that will introspect all contacts related to the channel and prepare the desired features set on the factory. It also has wrappers for AddMembers and RemoveMembers. Missing change notifications though. http://cgit.collabora.com/git/user/xclaesse/telepathy-glib.git/log/?h=contact-list
