Nice idea, but then you'd only be able to find the original perpetrator. The illegal copies still would be everywhere around the P2P networks. Hmm. You'd need watermarking software that can be automated. Each sale then should generate a unique watermarked texture file, and then it must be zipped and a unique link must be provided to the buyer. The problem is that the buyer should have ample time to download the purchase, say at least 24 hours. During that period, a hacker might be able to steal the file - it all depends on how well the Web server is secured. A couple of months ago I discovered that a certain merchant server wasn't secured, I was able to download her products by typing a direct link (for the record, I deleted the downloaded files and warned the merchant). Quite a few pitfalls.

The pen is mightier than the sword. But if you literally want to have some impact, use a typewriter
