I have been working on it on and off for quite some time. Mainly off,

I can share my "svn diff" with you off-list, if you'd like.

Well, the approach that I taken is to build an ra-layer shim; for
every function FOO in the ra vtable, it exposes FOO, packages
FOO's parameters up and sends them down the wire to the remote
service, which reads them, calls ra_local or ra_dav's foo(), and
then packages up the results, sends them back down the wire to
the client, which unpackages them and returns them.

This is the typical "client stub/server stub" RPC model.
One of the principal drawbacks to this model is that callbacks
are a hassle, and of course, we've got them.

The interface is also fairly wide (the commit editors are
what I'm currently bogged down in).
