Would it be feasible to create a kind of p2p digital trading card using some of the concepts from Bitcoin? I have been thinking about this, so I wanted some feedback. Here's what I have in mind.

Collectors collect, sell, or trade the "proof of ownership" to a digital asset which is stored in the network. Miners mine for the "right" to introduce new digital assets, or rather "proof of ownership," into the network. The idea would not amount to a currency, but it would serve more as a digital approach to the old concept of trading cards.

Of course, people could copy the digital asset itself, but the "ownership" would be limited.

So, what say you all? Dumb idea? Not feasible? Cool?
