Thanks for that explanation.  This would be very useful to a lot of
people, it sounds exciting!

So the idea could be, every user's workstation in a scientific lab
could be part of such a cluster: at one level it's their regular
desktop machine, but at another level it's also a high-performance
computing cluster.  Much better than the current setup of having a
256-node cluster but also providing 256 separate workstations, one for
each user.  At an extreme limit perhaps several labs could network all
their machines this way to create an enormous cluster.  For some kinds
of problems the benefits could be huge...  

My own plans are a bit in the air, I'm moving soon, but I hope to have
some time in coming months to understand this better and try to
contribute in some way.
