i think the alliance if it exists should be of distributed decentralized molecular groups
This. We don't need a centralized foundation. Maybe Bitfunder (or another crowdfunding site) can fund specific projects/causes as the community deems it necessary. Of course, the benefit of a foundation is that one could build up a war chest for possible future use.
I don't think we need any new foundations, especially ones with 'war chests' - who is going to pay for this? bitcoin should be as 'light' as possible.
