Ummm, Geoff, if you confine TCP state to just the connection details then
yes, many firewalls can and do this now.

However, does SunScreen maintain state correctly for the applications using
the TCP stream too ?  i.e. will it correctly handle an FTP "PORT" command,
no matter if I send it in 1 packet or 50 ?
