Will, one thing you will love about this is:  I said it's "free", but actually not quite, nothing is free.  But I have analyzed the cost of sumbitting a DNS record, and it comes down to about 1 micro sat.  Imagine doing something pretty useful for 1 microsat, and how granular an economy you can make.  Then we start to price everything in microsats, get a full ultra micro economy gong where the units do something useful.
