I wouldn't go for funding. Porn seems like the sort of thing you can bootstrap yourself. Hell, it seems like the sort of thing that would bootstrap itself. It also seems like the sort of thing that doesn't need a huge amount of attention (set up a simple uploading video server, set some upload caps so you don't get spam, and check back on it once in a while), so you can do it while you work somewhere else.

Dang, this is starting to sound like a not bad idea.

(I'm with vaksel too: remember Betamax? I don't, but I've heard stories that porn didn't choose it, so it died.)
