Well, unfortunately, one of the things that makes us fear the consequences of this program is that there's ample historical evidence of a lot of slip-ups--people who have the same names, even if they're spelled differently. We can think of names in all cultural traditions that can be spelled different ways, and you can find yourself in a very difficult process to prove to the authority--it could be Homeland Security, it could be here in Canada, too--that you are not the person whose name is spelled a bit differently.
