Yeah, you are right the offer is only for US people right now, but you never know. When they were looking for beta testers for Windows Live Mail, I believe you had to be a resident of US only, but I did get an invite to join it. It might not matter that much, because they do say 'If you are selected as a beta participant' (or something like that anyways) you are going to get the product key... only time will tell.
