"Could this explain how most of our stuff makes it to P2P?" I doubt it. The session cookie times out if I mail to a 2nd machine and wait 5-10 minutes. It's a simple case that some folks do share. Either deliberately, or because they give a copy to a friend who shares that. Whats really funny is when an illegal downloader mails you and asks how you use the freebie. Or if it's an add-on can they have the original product!

Pinky - you left the lens cap of your mind on again.
