Regarding fair use I suppose it depends on which country you're (plural) 
in.  From

Can I claim that my copy is fair use/fair dealing, or de minimis?
Unless your activities are explicitly allowed under law, there is no

suggest you get on with it, noting at the same time that my legal skills 
are nowhere near as good as my computing skills, which is really saying 
something :)
