Somebody said something about paying a gas bill with PND a few posts back. That got me to thinking. It's one thing to get people to pay with PND and quite another to get merchants to accept PND as payment.So I think that what would make PND a really usable currency would be a way for people to use PND as a payment vehicle and have merchants get paid in their native currency if they weren't accepting PND.

If the process was black boxed as part of the transaction so payer and payee weren't involved then PND would have the potential to gain universal appeal and would be set apart from other crypto's. Undoubtedly a Dev's nightmare, but hey, you dudes are up to a challenge are you not?
