That is an interesting optimization.  I could imagine a server that  
receives a presence without caps sending a disco#info to the client,  
then adding in caps info to their presence magically.  The server  
would then have to listen for and respond to the disco#info requests  
to that hash node, since the client is unlikely to do the right thing  
with that query.

You would still need the hashes, since one server would not be able to  
trust another server not to be polluting the hash cache.
