Entrepreneurial Project

As I might have told some of you, as part of our MBA we have to form teams, come up with a business idea & business plan and present it to Investment Bankers, Venture Capitalists and Private Equity people.
Right now we are in the process of forming the teams. It works in a way that people who have an idea pitch this idea to us to try to get other students join their team.
I have set myself a deadline until Saturday to decide which team/business idea I want to join.
So far the following business ideas are on my short list:
-Dr. DarkOh; provide quality assurance to prevent distribution of fake medication in developing countries
-FighterNation.com; Live-streaming of martial arts fights in the USA
-Social Finance; providing the link between social capital and enterprises in developing countries
-Kyoto : Trading "the dirty" for the sake of "clean"; carbon-dioxide consulting & trading for small & medium sized companies
-Media Distribution house for independent movies; connecting independent movie makers with movie distributors (video rental stores, movie theaters, etc.) by circumventing the big distributors (e.g. Sony)

It's gonna be a really hard decision to make...but if I don't do it now, all the good teams are gonna be full.

Exciting, huh?! What should I pick? And, does the team that I pick really want me to be on their team?

I will keep you updated!
