Basically, you would do this the same way as other people.  Do a disco query 
to your own bare JID, to retrieve the node.

I assume that then you should actually retrieve the avatar in question, so 
that the client can correctly display the "current" selection.

And you would have to subscribe to your own avatar metadata, so that if both 
clients were logged in at once, a change in one would reflect correctly in 
the other.
