This is a really cool idea, but I'd like a bit more storage, and less cost, before I sign up. If I could get 3TB for $15/mo, I'd be there. 3TB drives can be had for $120, and I'd like my cloud storage to be competitively priced.
Offloading my torrent collection into the cloud sounds like a great step forward, but not if it results in me paying more.
Amazon's S3, which presumably has scale advantages over put.io, charges $80/TB/month just for storage. put.io charges only 60% of that with data transfer included. Based on that, I doubt your wishes will come true any time soon.
S3 is one of the most expensive ways to store and transfer stuff though. Not to say the original poster could find that pricing, but if S3 is your benchmark you can save a lot of money.
I’m assuming that the service cost doesn't come primarily from storage, but rather from bandwidth usage, and the increase in hardware requirements for handling a larger number of torrents.
