Great comment to the How To Make Money Online or “the secret of making money in the skin trade”.
A better idea…
Build a content-management system geared towards porography with an e-commerce engine, graphics-rendering system, tracking system, etc. Once the software is in place, charge for the class as this fellow is doing and also have higher-end classes for customization of the backend (Interwoven & Vignette rack in alot of bucks doing this). One could also then hire out consultants for customization which the less tech-savy would need (such as WebCrossings does).
Which would sure make for fun consulting jobs.
