Good to know you think it was possible. I know in the case of Ultrix and HP-UX lots of external folks licenses small things like Mentat, MIPS etc. For instance, one of the Ultrix and Alpha bug-a-boos was the MIPS compiler, which leaked into the IP stream along the way. As far as I remember from my Locus days when we had just about everybody's sources from IBM to Sun, the problem was the license was not just the OEM and AT&T, there was always the sub-licenses from some deal or another that the OEM had cut at some point.
