Related to this, i was wondering how in the avatar use case would  
work in SPPS. When you log on with a client, how is the client  
supposed to know whether the avatar metadata of its contacts changed  
or not ? In the presence-based JEPs, the last hash was automatically  
sent with the presence of the roster item, so you got that info every  
time. Now, it seems that you have to query every contact at login  
time (which isn't really feasible).
