I have to echo what's been said - although warez are repulsive, increasing protection doesn't help. Firstly, it will be cracked; secondly, even if it CAN'T be cracked, you don't necessarily increase your sales very much. I've always believed it a total fallacy to suggest that anyone who accepts a pirate copy of anything would actually buy the product if the pirate copy wasn't available. Thirdly, what you DO do is piss off royally your actual legit customers. Even if the registration process is as simple as you maintain, it is very distasteful. The CL line above is "it sounds bad but really it isn't such a hassle as it seems" - that's not the point. It's what it seems that really matters. The image projected is really very bad.
