I think you should extend struct xsocket with jid. Unfortunately this
breaks ABI so MFC is not possible.

That being said, IMHO this patch can be committed to -STABLE if this
feature is that important, but -CURRENT should get implementation
mentioned earlier.

I can try to write a patch in a couple of days (or this evening if I
find the time).
