Definitely. p2p is absolutely the way to go. I live near the Sony lot and they're STILL in a shambles, their company-wide system down, doing stuff by pen and paper!
I'm actually curious to see if any large companies will see decentralized storage as the way to go in the near future. If the tech is sound then it sounds like a no brainer, security wise, but the idea of decentralization seems to run counter to their very centralized mentalities. Enabling the little guy to be a part of the storage of their files seems like a hard sell to begin with...; )
I think with the right pitch, Storj is capable of making inroads. At the start, I think Storj should consider approaching not-for-profit organizations like Archive.Org and Freemusicarchive.org. I'm sure they'd be more receptive to a cheaper, decentralized tech. Once they're on board, it would be easier to approach medium-sized firms.
