I do have access to a properly qualified authority on software copyright laws, but only for UK law. If there's a UK specific question someone would like to ask then I can try to get it answered. What I don't know is which country's laws would be applied if, for example, the vendor is based in the UK but the broker is based in the US, if the license itself didn't explicitly state which country or state laws would be applied. Maybe I should ask that first. Yup, it's complicated!
