Your idea is interesting, but frankly, I don't get it. Your resume and your website do not hint at your having the money to sponsor the groups. You do not tell us how giving up a percentage of our companies is going to benefit us. The money is small - I could work on the side and make that money every month.
What is not clear is this:
1. Do you have the money for this? If so, from where? If a piece of software needed additional funding after 6 months, would you be able to do this (like pg put 50.000 in justin.tv)
2. Do you have the marketing reach? Will affiliating myself with you give me greater marketing strength?
3. Do you have access to legal information and advice? Can you offer this to your startups?
4. Do you have any connections to Venture Capital? Do you _know_ about venture capital, such as to give good or bad advice?
