Thanks for answering, I'm very happy you're upfront with addressing concerns from fellow (more paranoid) bitcoiners.

Last question, I promise: are bitcoins liable for sales tax in Norway?

Most things are liable for sales tax in Norway, even gold (e.g. smuggling gold into Norway is big business - the street-price of gold is 25% above everywhere else). Are bitcoins exempt, and do you have any definite official confirmation stating so or do you have good lawyers advising you that it is exempt (with a reference to a specific law/paragraph that obviously applies)?

If you are uncertain, you are running an extremely large risk which could end in large losses for your customers and personal bankruptcy for the proprietors (not to mention criminal charges). Getting in trouble with the tax authorities in Norway is extremely serious...
