Real experiments would come later when entire ISS lab modules are attached to the station. Minor league versus Major League. Correct, real experiments = serious dollars.

I'm skeptical. I'd like to see some corporate investors, or sponsors other than Pizza Hut.

Japan has a science module ready to be attached to the ISS. The EU has a science module. China is thinking about a science module. National science modules. That's participation in their eyes, after America [Canada, too, of course] and Russia finish building the station.
