Does anyone know of a Wordpress theme and/or plugin that would allow you to set up a tube site that automatically updates with YouTube videos based on keywords? I have a mainstream domain that I'm not using and I'd like to set it up as a tube site that has clips from a specific category that get updated regularly so I can just launch it and walk away.

I think I've heard about a way to do this but can't find the info now from searching. I am also familiar with the Free WP Tube Theme but as far as I can tell you must add posts/clips manually to that and I'm looking for an automatic solution.
