You don't have to use the IBM version, but few, if any of the
truly public domain TCP stacks will work worth bothering with. We
use the FTP Software TCP stack, and I know others that use
Beame&Whiteside and Novell's LAN Workplace code. As a university,
you might seriously look at the FTP Software stuff; it's
reasonably inexpensive, and it`s really high-quality code.
