As noted in my talk earlier, SVK is a really handy tool for building remote operation on top of subversion. If you haven’t tried it yet, you need too. I’ve just tried it and been absolutely blown away by its mirroring abilities.
I committed a change on a local copy of a mirror of XML-Genx. I then said
svk push and saw the changes go back from the mirror to my master repository. I ran svn update in a working copy attached to the master repository and there were the changes. This rocks. Everybody needs SVK!
