Can they buy discs from second sources?
This reminds me of Japan. Years ago a convention promoter from Japan wanted to publish CDs of my toons via an animated venue. They have conventions there where people traded CDs of like 10 minutes of animation and shit. Fucking HUGE industry. If publishing these mini discs is easy you can hold onto your hats cause it'll be an even larger industry of trading and you can bet some kids will get their hands on them.
I buy toys from Japan and each toy comes with a mini-CD of the theme song of the tv show or movie. Some have vids on them. Sometimes fans make their own along with their costumes (

This P2P could be a problem for parents and we need to make sure it don't.
