Came across this on Bloomberg and thought it may benefit Ning sites with large video libraries as well as locating other videos on your subject from across the web. Tablet and mobile widgets available as well. No prices given (must email) however someone here may be interested in taking a peek. Let us know :) http://www.taboola.com/
I'd be interested to know what the pricing is like. Let us know what you find out!
Ha! One month and no response. Obviously they're not interested in a small site such as mine however I wish one of Ning's large video sites were testing it out. Oh well; nothing ventured, nothing gained.
