Intalio|BPP and XMPP

This subject is dear to my heart but frankly low level priority.

I looked at a way for our product, Intalio|BPP, to interact with a XMPP server. Apparently, there are some libraries that deal with this. The XMPP4R library, the XMPP lib that comes with ServiceMix, are two alternatives.

I tried to use XMPP4R with JRuby, but apparently there is a bug in JRuby that makes it hang. I never got the message through anyways.
I don’t feel like playing with ServiceMix.

So, to the heart of the matter: I asked the guys on jabber.org if they have a WSDL to interact with the server.
I understand that the server may have bindings with XMPP, eventually HTTP ?
I have seen reports about Axis2 supporting XMPP as transportation layer, so eventually we could get that.

What do you think ?

Now the folks on jabber.org never came back to me. Am I missing something ? Is there another place where I should be looking ?
