If done properly, that's actually an easier task: you build the

If you build it into the browser, how do you revoke it when someone
throws 2000 PS3s to crack it, or your hash, or your [pick algorithmic
mistake here].

If you use bad crypto, you lose no matter what.  If you use good
crypto, 2,000,000,000 PS3s won't do the job.
