I don't see how that would be at all useful.  At least the FreeBSD
kernel resembles NetBSD in 95% of the code.

It might be good for some ideas, in the same way that SCO SMP and
Solaris might be good for some ideas, but for actually borrowing code,
and finding out which parts of the kernel source need protecting, it
would be mostly useless.
