Yes, though strict hyper-computation is not possible in our universe,
limiting us to the more conventional kind for practical purposes.

There is some very interesting research (sorry, no links) that
suggests that it is possible to approximate hyper-computation on a
conventional computer with an error bound that asymptotically
approaches zero. For many potential applications of hyper-computation,
this would be perfectly adequate. The catch is that the conventional
computational models you would want to use as your basis have not been
studied much, so there is a lot of work to do for it to even be

This particular topic, approximated hyper-computation, is very high on
my list of things to work on if I ever find the time.
