If the other clients cache the capabilities... what happens when I
upgrade my gnomemeeting that 'only' does h323 to the upcoming
gnomemeeting that also does sip?

Disco features would solve my caching question.

Hmmm... closing the voip client is perhaps not a good idea. Jabber
probably won't be the only way to access someone through voip.
