It is certainly on the cards; Arthur Norman did a prototype of such a
thing way back, though I don't think it would work any more.  I sketched
up a rough draft of a design of one when I was working at Acorn, but left
before I had a chance to do anything about it. (It's too big a job
for spare-time hacking I think)

My feeling was that it would be relatively easy to page code off the disc
but data would have to stay in Ram.  And the code had better not be
squeezed or even that wouldn't work.  I'll see whether I can find my
design document in my old mail archives.
