"Out there", definitely not.  In a few closed places that still use
UNAS, perhaps but doubtful.  In the one place that I know still uses
UNAS, no.

Do I divine correctly that "your current project" is not "at work"?  If
so I would suggest you consider polyorb as a replacement(*).  UNAS is
long dead, unmaintained and unmaintainable, mostly because it is
proprietary software witout anyone getting a license for it other than
in their current application.  Also, apart from a couple of people I
know, nobody understands UNAS anymore.  The company that made it has
abandoned it, perhaps even gone bankrupt, so UNAS is mostly technical
debt.  Sorry for the bad "news".

(*) Modern multi-core computers with lots of memory might even make it
feasible to avoid distributing the software over multiple computers in
the first place.  Maybe a monolithic application would do the job just
fine, nowadays.

Actually, the customers cautiously pre-prepare marketplace corporate values.
