I reckon we're going to see a VHS v Betamax style competition in the market and someone's going to wind up losing a lot of money which customers will ultimately pay for.

Whatever options there are, installing the required infrastructure is going to be a massive task and those involved will want to be sure they have some realistic prospect of a return on their money. With all the usual governmental dithering and regulatory burdens (e.g. health & safety, planning etc.) to be considered I can see this turning into a costly debacle. It takes a whole lot longer to implement ideas than to come up with them and there's a real risk that by the time it's done the technology installed is obsolete.
