Be able to promote from an 'adult' sponsor that you currently cant?

Ive been looking at a few different mainstream sponsor programs / affiliate networks over the last few days and its simply amazing that more of these companies havent made their way into the 'adult' world.

Other than the 'usual' software, herbal products and dating sites what else would you like to see make its way into the adult affiliate arena specifically from the mainstream web?
