I doubt that this works if you are behind a firewall or a NAT router ...

Google is using a nice technique for their Google Talk integration in
Gmail: they send out a request to a file of virtually infinite size
that is empty and only sent very slowly, just so that it doesn't
time-out. Now they can simply push JavaScript code into that stream
that will be immediately execute on the client. No need of polling or
other dirty tricks, just a plain http request. It would be cool to
have something like that in Seaside as well ;-)

Cheers,
Lukas
