Note that this is a non-trivial issue by itself.  At a *minimum*,
you'll need all the checkpoint-restart code.  Plus, if the process
has any open TCP connections, *those* have to be migrated without
causing a security problem.  Good luck on figuring out how to properly
route packets in this case - consider 4 nodes through,
you migrate a process from to,  How do you make sure
*that process*'s packets go to 0.3 while all other packets still go to
0.1.  Also, consider the impact this may have on iptables, if there is
a state=RELATED,CONNECTED on 0.1 - that info needs to be relayed to 0.3
as well.

For bonus points, what's the most efficient way to transfer a large
process image (say 500M, or even a bloated Firefox at 3.5G), without
causing timeouts while copying the image?

I hope your research project is *really* well funded - you're going
to need a *lot* of people (Hint - find out how many people work on
VMWare - that should give you a rough idea)
