I think the whole "do you own your downloaded content" thing is going to be getting attention these next couple years, hasnt bruce willis spoke out about it, wanting to transfer his collection to his family? There was something else I saw along the same light, but cant remember now....
We are being pushed into an age where we no longer own physical things, but digital items, downloads, movies, music - why the hell shouldn't they have a "value", why shouldnt we be able to trade them at will, like we do today (grrr, bloody music industry)

Luno, he he, I'd thought of using the blockchain as a public voting system (infact, I posted something on here about my idea for an internet land, I had that idea for the voting system as well).
Thats the bit I'm having trouble with - but I dont think I'd give you the private keys to my music collection that was worth 100btc (you could cash them out, and sell them/spend - music can become a currency, esp if it can be sent in the bitcoin blockchain as BTC), but I may share an album/track with a trusted friend or family member. Or sell just one album by sending it to someone for payment in xxxxx.
I think thats as far as I've thought with that idea.....
Stephen, completely forgot about namecoin

, timestamping, hadnt thought of that.
