I think about this sort of thing quite often, actually: Your fears are exactly why i've not signed it. I'm American, living in Norway. I don't really plan on living in the states again, but I very much want to be able to visit family. I already wonder if that doesn't put me on some sort of secret list, but there isn't a decent way for me to find out. I don't even feel I have adequate representation anymore - I can vote based on my previous address in the US, but I highly doubt I'd be listened to. Not that it was adequate to begin with, but I at least had the facade.

It is really unnerving truth be told.
