Comment(by johntyree):

 It can't be made application independent? Isn't this kind of thing
 supposed to be what DBUS is all about? It seems like we should be able to
 just watch for network status updates on the session bus and act
 accordingly.

 Beyond that, I think the ping solution is an excellent and simple one. We
 can just ping the logon servers. If they don't respond, we go offline for
 that particular account and continue pinging every few minutes to see if
 they come back. Is there a reason we can't implement that?
