	Indeed. I do this in two different places, between two machines at
home, and two machines at work.

	Someone mentioned that the problems with unionfs have to do with
two simultaneous processes accessing a union-mounted area, although I've
been using union-mounted source directories to rebuild the world for many
moons and versions of netbsd, and have never seen a problem.

	Of course, on every machine I use unionfs on, I happen to be the
only user who has an account. =-)
