UK TV Licence Payers should be able to watch BBC output all around the world on Mobile Devices - n'est pas?

But as discussed in this thread Beware 3 Mobile - #14 by DianaP - even the 3 Feel at Home offer, generous as it is, doesn’t give unlimited free usage abroad with no strings attached, which is what you’re suggesting the BBC should do.
I don’t have an axe to grind as I didn’t do TV in the UK and I don’t do TV in France either. But I can see certain practical problems, for instance how on earth can the BBC check whether users of their services in France have a UK TV licence or not? And if there is no way of checking,would it not be wide open to abuse? If there are going to be licences and rules, then I think those rules have to be enforceable, even if that means they are restrictive.
