IMO. The p2p business model is problematic in this case.

1 People need to incentives to join a p2p network and certainly to contribute storage+bandwidth

1* Reliably and privacy issues makes this a bigger problem (though p2p may also be the solution, it's not easily achievable)

2 This can't easily happen without investment. Marketing + setup without "hassles" is not cheap

2* Given investment, what are the assets of the investors?
