First off, this is a wonderful plugin and I appreciate how it works. For the deployment I'm working on currently, however, I have a minor issue. I've checked the plugin out of WP.org Subversion to make upgrading as simple as switching branches. The side effect is that SimplePie for WordPress doesn't ignore the Subversion files which broke this for a few minutes while I figured out what was up. Might be nice to ignore Subversion files in a future release.
