My main work setup today is actually a diskless (X11-less) OpenBSD
system.  It's just something I set up in a VM environment to learn how
to do it (I'm on a work laptop running Windows 10, as I need Windows
for some few work-related tasks), but it works just fine and I have no
reason to change it.  For one thing, it makes backups easier as they can
run locally on the server.

At some point I hope to buy I smaller dedicated server to run the NFS
server (and mail, etc.) but I see no real reason not to keep running the
diskless client in a VM on my laptop.  Heck, then I might even be able
to netboot the laptop itself without disturbing the Windows system on it
at all...

OpenBSD has this "dpb" thing ("distributed ports builder",
/usr/ports/infrastructure/bin/dpb, http://man.openbsd.org/dpb) that
does distributed building of 3rd-party packages.  It does exactly this,
sharing the sources over NFS.
