If I am not wrong, another one of the Channel Islands (Alderney) has plans to issue currency backed by Bitcoins last year. Not sure what happened to that proposal. But Jersey seems to be yet another Bitcoin-friendly place. Considering the difficulties faced by Bitcoin users in the United Kingdom, I would advise them to travel to Jersey, in case they need to do large transactions.
The Alderney plan got shut down by Guernsey who lords over it.
All of these places might be quasi offshore, but they're still somewhat dependent on UK banking. As far as I can tell plenty of IoM operations lost local banking too when their UK daddies got wind of it.
Until all of that shit is sorted out this regulation will look lovely on the shelf but won't actually be much use to anyone.
