So why can't you share the memory ?
Something pmap calling pmap on another box, over the network, and so on.
Of course this would be real slow over ethernet, but what about if you have a host which has multiple cpu's with dedicated memory for each ?
I think in those sort of instances sharing memory over some sort of "network interface" is an interesting idea and process/thread migration could be very sexy. But perhaps Linux cannot support that without huge rewrites ?
