I don't think that xmpp has external references in buddy list, am I wrong?
In fact, in XMPP there is no concept of "buddylist" document. Instead each user has a roster and can add/modify/delete individual buddies without caring about the existance or not of a "resource-lists" document.
That means 80% of open IM market didn't feel the need for it. With private IM networks, I couldn't spot client options for it (e.g., yahoo, skype, etc).
I would say 99% :)
