Future of Music T-shirts?

All this chatter of Mos Def and his album on a t-shirt makes us happy. Music Tee’s we spotted last week are coming out in full force. My next question is simple though: What stops people from taking a camera phone picture of the download code on the t-shirt without purchasing it? Similar to the days kids used to bring razor-blades into the record store and slide out the CD quick and undetected. I hope we don’t ever have t-shirts locked up behind security as records and other hard media (DVD’s etc) have now. I’m excited to watch for sales figures of the Mos Def T-shirt ($40) to see if it has legs.
