I don't know much about paysites, but I do know that mainstream viewers LOVE behind the scenes footage, outakes, bloopers, etc. I think a site with behind the scenes footage and pics and especially light commentary about the scenes would be a huge seller. Think along the lines of Cannonball Run's outtakes.
Someone like Lightspeed or another multi-site owner could easily build a "behind the scenes" site that stands alone, probably with a pertnership arrangement with their other sites (some content, etc), or as a value add site.
Adult sites are becoming so homogeneous that this would really stand out, and would probably be a great retention tool.
