Well, I do have the UNIX source license :-). It's somehow a weird
thing with those Ultrix sources, they sometimes materialize in
cyberspace out of nothing. I'm not even sure I have them or ever
had them. But it sure would be nice if Compaq could be convinced
to make this available. I guess that many, many classic computer
folks are walking on a gray area when using any kind of Ultrix
that they may have inherited with an old machine or disk or
purchased off Ebay or whatever.

I did find out/guess that kern_lmf.c is really the key to the
License Management Facility, the thing that among other stuff
keeps me from having more than 2 telnet sessions to my VAX at
the same time. One workaround for the telnet stuff, I heard, is
to simply replace the login program using some BSD sources or
whatever. I'll see if this will do. The kern_lmf.o is an interesting
beast that wants to be peeked inside to see what it does and who
calls it etc. I suppose it is not so critical after all if one
can make a dummy replacement for it.
