I'm at least aware of the following Single UNIX Specification compliant

  MacOS X
  Tru64 Unix

[1]: I'm guessing about Darwin, as a subset of MacOS X that contains all
the bits needed to make a complete Unix-like OS.  It may not be
officially recognized as compliant.

Not all versions of all of those are compliant, of course, but they all
have been or are currently (meaning, in some previous or current release
version) certified SUS compliant.  There are quite a few "Enterprisey"
corporate shops that put a lot of stock in SUS certification, so in terms
of widespread adoption in business environments for server
implementations, it's not something that "won't be worth anything to
anyone".  Whether or not that means it's worth anything to FreeBSD is up
for debate, I suppose.

I find myself wondering if the SUS is losing what technical value it may
have once had.  The fact that MacOS X is certified kinda makes me even
more suspicious of the value of the certification than I was already.

Of course, with the rate at which open source OSes like FreeBSD (and
other BSD Unix systems, and of course Linux distributions) progress, one
must wonder how SUS certification can even be practical in application in
the open source world.  Certification takes time and money, and would
need to be acquired anew for every release version (unless things change
in regard to how certification is applied).  That seems a little outside
the realm of reasonability.
