I will require some thought, but the approach I take (which is
effectively identical to Malcom's), the Plenitude is a set of
cardinality c (2^\aleph_0). The argument works within such a bound. My
reading of Tegmark and Schmidhuber is that they also have a similar
cardinality bound.

Could it be extended to higher cardinality plenitudes (if such a thing
makes sense)? I don't know without giving it a lot of thought (and
even then?), but I'd hazard a guess that certain paradoxes might step
in making the whole thing untenable.
