Well, inf is supported in floats because it is supported in the native machine double. I suspect that adding inf and -inf (and NaN) to integers would end up being a pretty heavy-weight addition.
On the other hand, my quicky off the cuff implementation of InfDateTime is, in fact, a universal infinity -- i.e. it compares as greater than any other object, not just a datetime object. I did that more because it was easy than anything else, but perhaps it could be generally useful to have a Inf and -Inf object, kind of like None.
Or it would just create a huge set of confusing corner cases :-)
I would much rather see a infinite datetime object that a big discussion about the implications of a generic infinite object -- it is focused, has proven used cases, and wouldn't impact anything beyond datetime.
