What about support for Muji (multiuser Jingle) http://telepathy.freedesktop.org/wiki/Muji ? Why is this XEP deferred and are there any plans to develop it further and actually adopt it? It's an important functionality that's missing practically from all XMPP/Jingle clients.
Can you please elaborate a bit, what problems cause incompatibility between Google browser XMPP/Jingle plugin (Gtalk) and clients like Pidgin and Empathy? I never managed to get a satisfactory experience between them.
