I've got a buddy who is webmaster of a smoking fetish site. They don't even have any nudity on the site, just women sitting around on their asses, smoking. He sells a half-hour video of a chick sitting on a fence, fully clothed, smoking cigarettes. He sells it for like $25. He's making enough on it that he doesn't need another job...
I own a small programming firm, so I work from home too. Freelance programming is a great thing to do at home, if you can find work doing it. And if you can stand the lack of human contact.
