The idea itself, as it currently stands, is an amazingly strong one that is relevant to almost everyone. Are you sure it's necessary to get so complicated so fast? I worry that perhaps you'll lose potential customers and mindshare by being too quick to "web2.0 it." For instance, I almost stopped reading this post after the first couple sentences - the information was in the wrong order. Tell us the simple version first, then tell us how it will grow.

I hope this doesn't sound rude - I don't mean it to be. I really like your idea.
