It's going to be interesting to see how listener verification will be accomplished for BBC Radio on wifi radio devices. My guess is that any of those devices that run on Reciva, or that are made by UK companies whose databases are also hosted in the UK (Pure, Revo, Ruark, possibly Roberts) might run into fewer problems, but who knows.
With television, it gets stickier, because the licence covers an entire house, including (if I understand this correctly) children in university. Which means that, conceivably, the same licence number could be used to log in multiple times, even from multiple locations at once.
(I also wonder how the TV licence requirement is going to be dealt with by apps such as ToView, TVCatchup, and TVPlayer.)
