It's amusing to see people arguing for the benefits of SIP on this list
("I realize XMPP rocks, but don't forget, there is value in SIP too"!).
I'm not being critical at all, but it's not something we see every day
here. :-)

I agree with you that we need to determine what the overlap is between
Jingle and Zoep. Perhaps it would help for you to define the use cases
that Zoep is addressing. Is this something that two XMPP clients would
use to set up a voice chat or other multimedia session? Is it something
that an XMPP client would use only when communicating with a SIP gateway?

There are many ways that SIP and XMPP can interoperate. One way is
through gateways. I've defined a spec for that at the IM and presence
level (draft-saintandre-xmpp-simple) and I envision writing something
like that for multimedia sessions as well once the Jingle spec is a
little more stable. The gateway approach may seem ugly, but it is a
workable model (we've been doing gateways in the Jabber world since
1999). Better, I think, to let each protocol go its own way and interop
through gateways than to mix the two in ways that no one ever intended.

But I'm open to argument. :-)
