It was interesting to hear about the problems the BBC has in identifying the location of requests in order to both serve advertisements and apply DRM. We tend to forget that the BBC gets a near set amount of money with which to work, so spending money serving content outside the UK for nothing would be an expensive business. Also giving away content which is often under license agreements would also cause legal issues. I was interested to learn that the advertisement is coming on line now, due to the foreign office charging there policy of funding the BBC to deliver outside the UK.
