Great link and thanks! In November the CAA implemented new regulations for both recreational and commercial operators. It looks like the regulations in Air Navigational Overseas Territories Order 2013 (ANOTO) Article 73 recognize the registration of member states (bi-lateral agreements).

So I'm going to bring my drone and my certificates and shoot commercially unless anyone else has any more info on this. Of course much of it will be for my personal use, but if there is any awesome footage it will find its way onto my commercial website.

Thanks all and Merry Christmas!
