Fair enough, though I think eventually the SHA-3 winner will be
incorporated into hardware (or at least certain instructions used in the
algorithm will). I think waiting a few more weeks/months shouldn't be a
big deal, as the winner should be announced Real Soon Now, and then a more
informed decision can probably be made.
