Hi all,

In 2006, or thereabouts, I had an idea for a computer which you could
'rewind' and take it back to any earlier instance. It would do this by
logging every memory write, and every hardware write.

Problems are that you couldn't run a network client like this, because
the state of the network would change in the interim. However, you could
have every computer on the network also rewindable.

The problem i
