If you're interested, I'm putting the finishing touches on my own and instead of selling it I'm looking to work with some people who actually run tube sites to perfect and test a shippable product. It's not WP. The whole WP tube site thing always seemed ridiculous to me.
It imports the entire databases of HubTraffic and XHamster as a base with the option to direct link to video URLs for HubTraffic. As for other sites, for now it can scrape TubeGalore for the vids, then uses custom embed code generators for big sites and some pretty accurate scraping for generic tube links. I plan on adding importers for other sites too but that's not priority right now.
The main advantage I think it has over other scripts is the way categories are set up. It queries with logic operators, so "Amateur Threesome" runs something like "('amateur') AND ('threesome' OR '3some' OR 'threesum' OR 'three some' OR '3 some' OR 'threeway' OR '3way' OR '3 way'). It also finds related categories for whatever content you're browsing, which I think will increase engagement a lot.
Here's a screenshot of what it looks like right now. Obviously there's some weird stuff going on but you can see the functionality with the related categories and all that.
