Keep an eye out for my Tube Video API product at
http://www.mftscripts.com/products/tvapi (you can join the newsletter to be kept updated about it), as I will be directly working with tube sites to index their videos and give you an easy to use CMS and system to legally add their content to your site without worrying. Video removed from their site? Don't worry, the CMS will know and remove it from your site also.
