Such a thing could be implemented, but I can't see it being accepted by a majority of peer nodes. My opinion is that we should not monkey with the code to accommodate human nature. If someone can't get their head around the fact that price is irrelevant then they should trade beenie babies instead.
But isn't worldwide acceptance the ultimate goal? Don't we want total saturation? If this is to be accomplished, then the protocol has to be presented in a way that is easier to digest for the average non-tech person.
Trying to explain to my wife that there are 100million satoshis in a Bitcoin. And that you can buy and send .001 bitcoin, which we are now calling a millibit is a disaster.
