I remember way back Palm selling books on SD cards. Don't remember if DRM was involved or what the books were. Don't remember how popular it was. I have one around here somewhere.

I'm sure as ebooks gain popularity you might see something like this, especially with traditionally pbook stores like B&N getting into things. What would be more likely would be a card (similar to a greeting card) with the books cover art, with a redemption code in it which would probably make the DRM aspects easier to handle.
