He he, well I guessed so. I just thought if it was possible for the 
server (or maybe an add-on app) to watch the running transports. If 
one crashes, it sends an unavail presence for that transport, and 
then attemps to restart it (and maybe email/jabbers the admin that 
problems are occuring). I think that such a tool would be _way_ 
handy, condisering how often ICQ-t, AIM-t and IRC-t on jabber.org are 

but I dunno that much about how transports are realized, so I don't 
know if this approach is feasible at all...

Of course, I'm aware of this.
