Sorry for the delay in landing #6995 - there are a number of
improvements I keep trying out, delaying the patch.  But, this time,
it's almost ready.  I had one volunteer on IRC who might be able to
help me test before I ask for wider testing.

I am in the same situation and would like the same feature, but I
don't think things are too possible with the current NM: see

It Just Happens - Network Manager notices a connection is down
(somehow? probably device- & kernel-specific) and starts looking for
new ones.  But applications probably won't like this.  There was a
huge thread on devel@ in Jan/Feb IIRC debating this, but basically I
think activities (the underlying APIs they use, mostly) will vary in
how well they deal with IPs changing and their network sockets getting
closed.

No idea, sorry, but I don't think your question is a conventional
one.  Jabber servers can be federated but I don't know of any that
are, nor if and XS's jabber server is.  But I think you're mixing up
"connected to a Jabber server / server-cloud" and "connected to an
AP".  The latter is a pre-requisite for the former but doesn't
necessarily imply reachability of the former.  So if you change your
AP, that may have nothing to do with connectivity to the jabber server
by which one was chatting to an overseas buddy.
