It's a great little tool - good work! A couple of suggestions:
* Have an option to include the diff in the RSS feed itself. This would be more server-intensive for the SVN server, so you'd wanna ensure that your caching is up to snuff. * Make the display of the diffs at http://svnfeed.com/svn2rss/diff a little more user friendly. For example, this is how Trac does it: http://open.silverstripe.com/changeset/62484
