associate show with prio and automatically change prio
even peter thinks it's a great idea..
gossip does it
and it sure makes good use of priority
the issue has been discussed recently in ML
we should just send a presence with new <priority/> on show change
If two or more available resources have the same priority, the
server MAY use some other rule (e.g., most recent connect
time, most recent activity time, or highest availability as
determined by some hierarchy of \<show/> values) to choose
between them or MAY deliver the message to all such
resources.
so if I have gajim at house away and at work online but go away on work and start going to house, it's up to the server what will happen. so we may want to avoid that, we should be clever enough to see the show and prio of the other resources and make sure we're always one point less or so
