Hi Ian!

Hmm, don't know. :-/

IIRC InJoy sets the default route to a fake IP that is "assigned" to the serial 
device it uses for connecting to the Internet. If a program wants to access a 
computer that has an IP address not existing in your (sub-)net, the request is 
forwarded to this IP (111.222.111.222 IIRC), and triggers the InJoy DoD 
feature. So this is simply a question of routing.
