FWIW, I've done some work in the direction. I have a proxy-server
running which attached to a database which will respond to GET
requests from the database and forward POST et al to the main server
(and update the local database accordingly).

It's not totally functional yet, but it's mostly just missing round
tuits. As for tracking updates I have ideas for a Proxy Invalidation
Protocol which would allow efficient transportation of information
about data that has changed.

Whether it will actually work is another question entirely...

Have a nice day,
