That's correct. There's no way for a server to communicate back to the client asynchronusly in the case of a firewall.

Hey man, blame the firewalls not the protocols. :) The protocols are perfectly capable of it, it's the fact that all ports on the client are most likely blocked so nobody can build anything around the assumption that they'll be able to communicate back. I agree it sucks, but that's what years of virii and DDoS trojans has brought us to. :\
