Yeah, it needs support from: - financial institutions - approved by gov't as payment scheme (protected by law) - accepted by the commercial entities (shops, etc) - and most of all, accepted by the customers. they need to trust the thing and it has to be designed so it's easy (and beneficial) to be incorporated in to one's daily life. you can't just spew out a new technology to the market, claim "first!", and expect a "win.".
