I've been fiddling around with SureFlix's BYOC offerings. Their Build Your Own Custom Theatre dealio. And it's pretty cool. And you can select what kind of content you want focused on it - put together custom, individual theatres focused on particular niches.
Pretty nifty so far, from what I can see. And I'm a needy bastard too and have e-mailed them about this and that and they've always been eager to respond and accomodate so you might want to sign up for SureFlix, ask particular or specific questions about what you're looking for and see if they can swing some stuff for you that isn't offered already.
