copy rights may be federal , or international, but employment standards are not !

So a permanent employee, a temp, a contractor, etc may have different rights in each jurisdiction!

big flap here about news & magazine articles sold to publishers, who then re-used them on the net ! selling one time rights , or even re-publish did NOT giove the publishers exclusive & perpetual rights in all media !

I think programmers may be the same, if I write a block of code as part of a project, on your computer, you may have all rights! but if I bring you a disk, then I may have my own rights as well as you having yours!

too messy to call!
