Setting up Subversion with multiple access methods

One thing that makes subversion (http://subversion.tigris.org/) such a powerful revision system is it’s ability to permit multiple methods of access. Https, WebDAV, SSH and svnserve. In spite of svn’s ability to support multiple access methods, doing so simultaniously can be quite challenging. Typically one will run into permission issues as the http(s) access will all be written to the filesystem as the user running the webserver. The SSH access will all write to the filesystem under each users given account.
