Both Caldera and old SCO employees were heavily involved in the
development of Linux as a enterprise scale platform. ( As if you haven't
read about the Trillian Project which ported Linux to Intel's IA-64
processors...
http://twiki.iwethey.org/twiki/bin/view/Main/TrillianProject )

Dr. Stefan Hildemann claims to have had a chance to see SCO's code show
without having to sign the NDA; he has posted his impressions (in
German).

Thanks to Robert Taylor this English translation of the posting
    ... The crunch, however, is a function of the scheduler, which is,
    over a length of about 60 lines, indeed identical except for slight
    differences. In this section, there is also a whole lot of
    corresponding comments...

Well, one of the core SCO developer responsible for the development of
the SCO Groups current Unix Intel port, also contributed to the Linux
kernel. Compare this post of Jun's including the comments
http://www.geocrawler.com/archives/3/5312/2001/1/0/5052740/
To this actual part of the Linux 2.4 kernel
http://lxr.linux.no/source/kernel/sched.c?v=2.4.18;a=ia64#L229
and consider the comment of Dr.Stefan Hildemann.

This raises more interesting questions. Since the SMP scheduler in
question was specifically written directly for Linux kernel, and both
Caldera/SCO employees only added patches, does it not seem more likely
that if there is common source and comment then it is likely that the
source in question was copied from Linux to The SCO Groups own Unix?

Yes, the difference is that the Fair Trade Act makes it a Federal case,
very hard for the SCO Group executives themselves to dodge.
