So it's mostly come from hard core jabber folks :) We are targeting
people that know nothing (and don't want to learn) about the Jabber

The resource and priority settings are therefor typical things that we
do not want to bother the user with.

This sounds all good, except that I want to be able to also unlock the
window if the user connects again with a client with higher availability
(ie. higher priority).

Would be very nice to be able to do this without closing the window. And
it's possible by just resetting it when you receive a presence with a
higher priority then the one you are currently locked to. However, from
what I understand this doesn't comform with the spec.

This sounds like a work-around that the user has to handle himself
everytime. This is really hard to solve in a nice way, other IM systems
don't have the problem since they don't allow multiple logins.
