The problem with that is that presences are probed when you sign in instead of the server keeping track of presences, which would be far more efficient. > Instead of probing, a server could store the state of each contact.

One of the problems you also have with presences is that you only get presences for only contacts - not for offline contacts. So you can't know if somebody is really offline or if you just haven't got the presence yet.

Which still does not solve the presence flood. -- Jonathan
