By the way, what you possibly could do, which would at least solve it 
for TCP/IP, is if you can setup a virtual network on the MAC, and then 
have the MAC route between the WiFi network and your virtual network.
But it will not work for DECnet (for obvious reasons).

But I don't know how you set up a fully virtual network to start with.
