Like others here, I can't see why Auntie doesn't make all of it's library of programs available for a small "on demand" fee - which can be varied depending on where the viewer lives....after all, those in the UK originally paid for the programme making (at the time) via the licence fee...but those in other countries didn't so, no problem with a two-tier system.
BBC Wordwide has no problem making money out of old programmes when sold on 5" bits of round plastic & aluminium....so, why not go the whole hog, cut out the wasteful resources "medium" and give people downloads direct to their new fangled flat-screens connected via the intra-webby.
While they are at it, do the same with live broadcasts and bingo - everyone pays something when they watch the BBC and we can all forget about the licence fee...
(And by the way, the DAB specification allows for subscriber access modules, but no-one has implemented this on a product yet - so BBC Radio will remain free for now. I seem to remember Bloomberg originally broadcast on DAB, and you needed a subscription to hear it. As no-one had the right "set" it didn't work out for them).
