Just a slight clarification... the problem is not that you need a UNIX
license to get the XINU sources, but to get the distribution from
Prentice-Hall which includes some UNIX-derived cross-development tools.

Some time ago, someone actually posted (or offered to mail) the XINU
sources. He had permission from Comer and there was no legal hassle since
he was not distributing the cross development stuff.
