This is moving into the broader topic of exploiting position, which is what much of floating really is anyways.

I agree that holding draws and repping w/ scare cards can be considered floating, but to me that's just playing a draw/whoring position. If I flop a draw and am cbet into, I tend to raise the cbet unless opp is very aggro (and in these cases it's often difficult to float against them anyways as they will follow on the turn).
