In other words: Let's say I want to invest $100 in SmallCompany.com, for the equivalent 100 shares. I make that bid, and if SmallCompany accepts the bid, then I give Me-VC.com (the accredited VC company) $100 and Me-VC would make an equivalent investment in SmallCompany of that amount, for that number of shares. If SmallCompany exits, I get a return commensurate with the number of shares Me-VC invested for me.
Edit: I developed a site to back this but I've been searching for someone to co-found on the business/legal side, which in this case, is by far the tougher role.
It makes me mad that in a country that has nearly zero financial regulations from fleecing the poor, there are regulations from keeping the poor from investing in seed stage ventures. The rich can invest in Twitter and the poor are stuck with the lottery (i.e. mathematically constrained odds of 'impossible'). Fuck the rich.
The SEC regulates the American markets, but worldwide you've got plenty of options. One way would be to incorporate in Panama, Curacao or Cyprus, where there are not such limitations.
In fact, the whole 'accredited investor' concept is as far as I know limited to the US.
