How much do they have to actually stock though? 50-100k USD ($5-10 over 10000 screeners) is a good bit of money but they'd probably only pay out a tiny portion of that and compared to the budgets of a large blockbuster it's not that large of an outlay.

If they can reliably embed multiple private keys into the screener DVDs they could get by with having fewer account and using the combination of accounts as the key. Though really if they're able to embed a whole private key in a way that survives encoding why bother with the bounty, though I guess that saves them the trouble of having to go find torrents/rips themselves.

This is a brilliant idea! Since we expect only a handful of leaks, each screener could contain lets say around 100 bounties of $10, with 200 bounties total. Then the first leak would be worth $1000, the second leak $500 (expected value) etc, and the studio only needs to pony up $2000 in total. We are guaranteed to be able to identify the first leak, I'm not sure if we can identify further leaks (there is probably some kind of trade-off between payout for the first leak, total amount of bounties, and probability of being able to identify further leaks, but the mathematics of this is probably not trivial.
