Well, there are a few stacks out there already, yet the only one that is available for free is the ancient AmiTCP demo (AFAIK). So I am sure folks would give it a try if there is an alternative. Maybe you could also focus on an implementation that can properly run on a low spec Amiga (e.g. unexpanded A600), because I feel that's kind of missing somehow. Tried to run AmiTCP on it, and was hoping to be able to transfer some ADFs via ftp, but all you could do was "ping" without running out of memory. :lol:
So... I'd say give it a shot. If you need a beta tester, drop me a line... ;-)
