Sure, why not? It would probably be good fun to talk product development with the CEO of Apple.

Then maybe I can take a look at their implementation and see if I can secure it (standard consulting rates apply). Apple has a lot of good engineers, I bet they already know about the trivial stuff, so I could get right into the interesting problems.

I mean, a naive implementation uses bluetooth LE, but presumably users could just turn bluetooth off (among other problems). I can think of better implementations that don't require radio or internet to work. I think a smarter approach would be optical or audio encoding. That would make it reliable in concerts (where lighting and sound are tightly controlled), but not reliable enough in most police-state contexts (where lighting and sound are not tightly controlled). Fine tuning it further to ensure that it only works in the context of concerts should be pretty easy.

I haven't read the patent though, I don't presently have access to BBC.
