Sluggish, the problem here, it seems, is that some folks (unsatisfied perhaps with the result) are now trying to re-define the problem until they find a way that makes it not fly. Constantly repasting the 'tundra tires' puzzle is one method, another has to do with creating mathematical abstractions that attempt to violate the laws of physics by "just going faster" and pretty soon, people are throwing around concepts like 'infinite speed'.
Science is a harsh mistress. u*N is the law of the land, and no amount of mental bananay is going to get this girl pregnant.
