However, there should be a use for persistent store, for a remote encrypted database accessible anonymously.

The real questions are "how big is the market?" and "how much revenue is there in it?".

Something like this doesn't get made reliable by volunteers.

I think that the market is potentially large.

Ideally, the data is stored on a distributed data base, with some redundancy in case one or more gateways go down

Look in Schneier for secret sharing.

We won't have a copy of Schneier here for three weeks or so. Can you elaborate? However, almost certainly, the crypto aspects would be relatively minor. Most of the work would be in building a reliable widely distributed data base accessible over the Internet. When I last looked at this sort of problem, it was very complex. -- Jim Dixon
