@Kevin - I also have a problem with the "as long as they don't do it on wordpress.org" sentiment - *especially* now that plugins and themes hosted on wp.org can be searched/installed from within the admin UI.

Some enterprising theme/plugin author is going to have to write a plugin to allow for non-wp.org sources to be searched from within the admin UI, or else as time goes on, *only* wp.org (i.e. Matt) sanctioned themes/plugins will ever get any real exposure.

Also, I have a problem with Matt giving lip service to wp.org being a community-driven website, yet at the same time making unilateral decisions by fiat regarding these issues. I don't remember the community ever being consulted regarding inclusion of non-GPL (proprietary) or for-cost (premium) themes/plugins in the wp.org directories.
