"A standard protocol for machines to negotiate bitcoin payments for resources"

Great idea from Brian Armstrong of Coinbase:

1/ Seems like there should be a standard protocol for machines to negotiate bitcoin payments for resources.

2/ Examples could be getting access to wifi hot spots, your car finding charging stations, mesh networks (net taker/giver).

3/ Devices could be like vending machines, you drop them out somewhere, and they generate rent for providing resources to passing machines.

4/ Sample protocol (a) i need X, anyone have it? (b) I have X for sale at Y © I accept, payment embedded (d) I reject, stop pinging me

We are dying to fund people working on ideas like this, or like these or these.
