It's a very interesting idea, and I don't think anything quite like
that does exist yet.
One idea we've had knocking around for a while is to integrate dill
 with IPython to provide some sort of 'snapshot' capability, where
you can save the interpreter state and come back to it later. Of
course, data in files or on the network may change in the meantime,
but there are probably many cases where that's not a problem. If you'd
like to develop something around that - perhaps initially as an
extension , I think you'd definitely get some interest.
