I don't know if the governments of the world can do anything about this, but they're going to want to try. If they don't know how much money I have, then they can't know how much I should pay in taxes.

I think we're already starting to see this play out with Anonymous. They're trying to crack down, but having difficulty.

I'm interested in seeing how crowdfunding might work for projects traditionally funded by taxation. One example: http://neighbor.ly

Or science funding: https://experiment.com/ (formerly mycroryza.com)

Interesting to think about how beacons intersect with other interesting things. I see a flash mob app in the near future.

I like the idea of automatically recognizing a quorum based on sensors. Will make auctions and voting interesting.
