I see, so he's essentially proposing a memory to memory swap functionality as opposed to just memory to disk. It sounds like a workable solution, although it would require some engineering in the kernel paging algorithms. You'd also need to make changes to the scheduler so that you could intelligently schedule threads on the node where their memory is. It sounds doable, but it seems that this is a lot of work for kernel engineers to do that could be done by software that is NUMA aware.
