Someone correct me if I'm totally lost in the weed, but MacOS MacTCP
drivers do the IP/DDP encapsulation. Now A/UX translates MacTCP parameter
block calls to low level socket calls, and there's no code for DDP/IP
encapsulation as such.

Maybe something like that would be easy to implement, especially if the 
socket TCP/IP part would be streams based (which isn't the case just 
now).
