Much of the marshalling could even replicate what is being done by ra_dav
and mod_dav_svn. e.g. how we marshal 'svn log' over the wire. Just
substitute a pipe for a socket, and it is basically the same (minus all that
HTTP crap :-)

But yes: our XML stuff is an effective serialization/marshalling format
which is already in the code. It is horribly unmaintained at the moment, but
I suspect that it is going to be "darned close" if somebody cares to
concentrate on it.
