Yes, most of the documentation is still at waveprotocol.org but will
eventually be migrated to the Apache Wave website
http://incubator.apache.org/wave/ and wiki.

Persistence is described here:
http://www.waveprotocol.org/protocol/design-proposals/wave-store-design-for-wave-in-a-box
It says "this file system based design is less scalable than a
database system like MongoDB and therefore we expect to revisit the
design later to scale it better", but I don't think anyone is working
on it.

At the time we implemented the file based persistence, mongodb lacked
the necessary facilities to acknowledge when data reached durable
storage. That has been added now and there should be no technical
roadblocks to implement the storage interfaces with mongodb. The code
is structured in a way that should make that straightforward if anyone
is interested in doing it.
