So the presence cache would be the way to go then?

And what would the best way be to detect a broken connection, especially
with TCP's 20 minute wait? Would periodic updates to the cache need to be
done too since s2s isn't always connected? Should they be scheduled w/ the
<x/> stanza I suggested? This could be hidden from the clients by letting
the servers add/remove it.

Are there any questions that I missed or suggestions that should be heard so
the Right implementation gets written?
