There are a few JID->OpenID services around (although they tend to be 
experimental, and thus not too reliable) for example 
http://openid.xmpp.za.net/ and http://xmppid.net/ . These are regular OpenID 
providers which use XMPP for out-of-band authentication, so it's a little like 
a gateway (XMPP <-> MSN for example) in that the XMPP part is hidden from the 
OpenID requesting entity.

I would look at what services like those do as a starting point for a JID-to-
OpenID mapping layer, and make sure that the XMPP stays hidden from those 
requesting OpenID verification.
