Thanks for the feedback guys.  One thing I'd like people to think about is concentration on the faucet versus concentration on using the system.  If you like the technical aspects of the system, no transaction fees and speed, attention due to the faucet isn't a long term sustainable solution.

The only thing that sustains the system long term is developing bona-fide usefulness.  When people want to use the system because it solves their issues better and more cheaply than the alternatives, that's what'll make everything work long term.
