Another interesting project along these lines is
DataHaven.NET. The developers recently created a currency-based marketplace for P2P encrypted storage, and have stated they're interested in integrating Tahoe-LAFS. However, it's not clear how they'll accomplish this.
Interesting. Though it does look a little like the project is dying. Also where is the github/source link?
One problem with their market approach is that they are effectively price fixing. It would be better to have the market decide the price of storage based on the provider's reputation/capabilities/performance etc.
It would be pretty sweet to have semi-autonomous applications that are able to negotiate their own data storage contracts via a nice API.
