A fried of mine is into the alternative sexscene (SM stuff...) and runs a club and a blog. Through him I hear a bit about the scene and meet some of the people. One thing I have noticed is that there is plenty of money in porn, and most of it is in specialities. The reason for this is that there is an abundance of mainstream porn available for free pretty much wherever you look, but if you're into something weird it is much harder to find, and thus there's a paying market for it. I heard the numbers for a site that does a weekly liveshow with some pretty serious SM and they are making very serious money.

I've also noticed that some of the consumers of the more specialised porn and upscale swingerclubs are wealthy individuals in their 40's and 50's. Naturally these people have a very open view on pornography and adult-oriented startups. If you try networking a bit in the upscale swingerclubs in the big cities and/or the well-run specialised sites you might find an investor. These people are mostly very open and very nice. Probably because they, like the gay community, are an outcast niche that has to constantly defend their sexuality.
