DHT storing the *data*.

Note that the ones you mention above seem to be pretty unstable.

?? This would of course happen incrementally.

If there are different hashes of the keys, this shouldn't be a problem.

The thing I'm looking for is some guarantees about performance. For DHTs,
they seem to be there, but for DHT + IP-based fetch I don't think so.

Or can you point me somewhere where that has been analyzed?
