I suspect it is the schoolkids and not student who cause traffic
jams.

That seemed to break everything... or did everyone just go to
lunch. Oh back again...

When I try to send (you're not available at the moment but it
doesn't seem to make much difference) it just hangs as if trying
to do something indefinitely.

TCP dump spews out the following....

Hmm a tcpdump of message Chas is just a UDP to the ICQ server.
Alex barps trying to get directly to him, and then sends via

Urgusabic it just spins and spins...

What is that 'win 0' I wonder....
