Please, anything but H.323. It is the most horrible protocol I know.

I would rather see the voice and video connections innitated through
jabber as SDP (session description protocol) message sent in a special
namespace object. With SDP it would be easy to cooperate with SIP
protocol, and all the signaling could be done via Jabber.
Using just RTP and SDP (or maybe SDP is not needed, tha same information
may be passed in special XML namespace) we could use PASS, I don't think
it would be possible with H.323.

And H.323 implementation in Jabber clients would be very hard. Starting
RTP-talking software from client using data from SDP description (or
some XML description) would be much easier.

We can also use jabber:iq:oob and SIP protocol, but IMHO Jabber with its
XML stream may be much better for signaling, and RTP is used for
transmision in any signalling protocol anyway.
