Hmm.  Are you offering to port Mach IPC to FreeBSD as well? :-)

Can't speak to that, not having seen it.  Got some pointers?

I'm fine with the notion of using IPC-based directory services, but it's
not simply a question of finding a tarball and committing it.  There's no
lack of standards, APIs, etc, to pick from.  Since you're pointing at an
Apple solution, it's worth pointing out that Apple has also been in flux
on the topic of directory service APIs over the last two years, trying to
move away from NetInfo and towards DirectoryServices.  One of the things
we're still trying to address for FreeBSD is how to fit into a world of
distributed directory services where, until the last year or so, it's
really been unclear what the most interoperable and easiest to manage
solution would be.
