This should be the News Of The Day in the whole crypto-space, IMHO - but alas it seems that most of the people prefer to invest their attention in trivial issues of all kind instead.
Prosaic contracts seem to me like an invaluable milestone for the upcoming mainstream adoption of crypto. Now we'd only need some real-world court starting to accept the undisputable evidence provided by Obyte's prosaic contracts. But I guess it will take a while before we'll be able to explain to courts how they could better do their jobs.  

As for the argument which has been made about the problem of determining who has actually pressed the contract button, this is a momentary problem to which there are surely plenty of solutions. For example authenticating the person through the phone capability to read fingerprints.
