Just a small clarification here. Bitcoin Wallet supports the customer side of the protocol since 2011, without any "Labs enabling"! This means you've got an install base of half a million devices that you can interoperate with. Sure, a lot of users will have Bluetooth switched off. The UI flow to enable it while paying is pretty smooth though. The merchant side used to have the Labs enabling but this is gone since a few weeks.
