I don't believe that svnserve uses sockets at all in this scenario - just
stdin/stdout. In which case it is pretty much as Pete so colourfully said,
you can have your way with the DB since the svnserve process is running as
the user and must be given read/write on the repo.

Actually tunneling the socket is the method I use. It's a two step process
and one not talked about in the book or the FAQ. First you create an ssh
tunnel to the svn server, then you access the repo via "localhost". It has
the advantage that your svn users don't need to have perms on the DB repo
files. And for the really paranoid, you can restrict the svnserve process
to only accept connections from localhost, thus the only exposure needed is

I hope I'm right, 'cause that's the way I'm running it.
