Alright.. just when I was thinking I was crazy I bumped into this post. I think it could be a fabulous implementation and a very profitable business . If you are still interested, please let me know. NOW is probably a better time.
My Reasons:
1. **Enterprise WordPress users** would be most interested:
2. **Hosting providers** could be major customers:
3. **Specific use cases** would drive adoption:
The key is that you'd be targeting the upper end of the WordPress market - perhaps 1-5% of WordPress sites, but these represent the highest-value installations.
