So far in AppleWin the emulation requires libpcap and the capability to inject and receive raw packets.

I think this makes it a lot more portable and able to use non ethernet networks (the above code only 
works on an ethernet card in promiscuous mode, no wifi, vpn normally).

I think that as long as the guest software runs, it is doing its job.

Do you mind giving me some instructions on how to run Spetranet (I have never used fuse before).
I'd like to see the code in a debugger.
