I thought about it half a year ago. Well, i tried it out and openmosix
and veserver-patch compiled. The Problem is, that the knowledge of the
context needs to be migrated, too. in a first attempt it would be
sufficient to implement this, but one has to thin about same context-IDs
on different servers in the openmosix-cluster. The whole Idea fits close
to the Ideas of grid technologies.
