Well, there's software that does that (or something like it), but not in BSD-land, at
least not yet.  Although I agitated hard to port what is now OpenSSI (see to FreeBSD back in 2000, they ported it to Linux instead,
sigh.  I would really love it if someone would actually pay me to do the port to
FreeBSD (or, better, to reimplement it).  But that's pretty unlikely.

So no, clustering support is thin on the ground for BSD.  Maybe someday, when Matt
manages to start work on his SSI stuff for Dragonfly.
