I have a business based in Jersey (thats Jersey the Island near England, not New Jersey USA to be clear

).
It's pretty easy to use local professionals to setup businesses, but do not think that the money laundering/KYC rules are any different than for any other developed country ie cash/fx transactions require full disclosure of identity etc. The same will probably apply for Bitcoin there, unless it's just being used to buy goods etc.
Also most of the local banks are subsidiaries of major global banking groups (for obvious reasons), so they will be under scrutiny from their HQ as to the businesses they enter into. If they don't like Bitcoin at HQ they will ban all their subsidiaries as well.
