Sorry, misunderstood your problem.

I started trying to fix all the warnings building it gives, and promply decided to rewrite the 
blasted thing.  Unfortunaly I know bugger all about tcp/ip etc, but I think using the file system 
extensions is an excelent idea (should even make porting unix tcp/ip progs easier).

If I can figure M$'s vtcp/vip vxd api's, it would even work under 'locked doors' :).
