	The original specification for the token was a pseudo-random
number. It gets transfered once (during the login process) in the clear
between the client and the gateway.

	You're probably aware that the connections between the auth
server and the gateway are always gateway initiated so "immediate"
would translate to "immediately after next command to the auth server".
