It's a possibility already, but it appears like the resellers also don't want to take the risk of giving warranty on overclocking. If they sell a card that's already overclocking-enabled, they'll have to buy the code from me at full price. Applying the change is a quick thing to do, but the legal part of it is that the reseller is now resposible for stability of the card. I'd expect that this will only be done if extensive tests are performed at the reseller's site, and these must be paid for in some way. Not exactly the thing you want to add to the price of a low-budget product.
