I don't know about it, except for NOW and SPRITE.  I would like to expand on
the 'Jail' concept whereby a virtual machine is spanned accross many physical
machines.  In this way the only processes that can move are in some sort of
container.   

The biggest advantage I think that I can bring is migratable networking sockets.
Also shared memory would be available across the machines (though I don't think
this is new).

There is a thread going on about 'fish' in hackers.  I had thought about the
problem in my GUI.  I may actually try to address it, since I handle
configuration replication and it would be a small matter to include the 
settings in 'rc.conf' and other things.

Good luck!

PS. When I do the next release you might consider trying it for no other
reason as to have a central console...
