I use my own svn repositories for all my development. I am looking for an easy way to keep the svn repository wordpress provides for my plugin synced up with my own internal repository. The desired end result being that when I commit a change to my own internal repository it gets duplicated automatically to my repository at plugins.svn.wordpress.org.
ANd just to make things fun and interesting, I do not have any access to the server where my svn repositorys are held, I use a svn hosting service.
Maybe the svn switch — relocate repository option can help you here: svn switch –relocate oldURL newURL . ( http://svnbook.red-bean.com/en/1.1/re27.html )
But… a lot more options here: https://stackoverflow.com/questions/580443/svn-one-working-copy-two-repositories
