Now that Scan are accepting bitcoins have you considered talking to them about their experience?
I know they are just using Bitpay at the moment, but if their acceptance of bitcoin is going well then perhaps they would be willing to co-sign a letter that asks UK banks to be more open to the idea that there is legitimate business that takes place using bitcoin.
Thanks for the information. I will be in contact with them. I am in touch with a few UK bitcoin businesses.
