I (Marc) was the one trying to come up with a

I don't think the general concept of an Omega Point
neccesserily implies Tipler's particular scheme. As
you point out, it appears that the specific model that
Tipler gave his book has been falsified by empirical
observations.
The general condition for an Omega Point is simply
that the average rate of information processing per
unit space approaches infinity in bounded time. There
could be many different ways that this could come
about.
