Thats true, but if SR uses the basic system that most people use, you can buy it from yubikey. it wont tie any key to anyone. Yubikey has over 1 million users. I think it would be next to impossible if not totally impossible to track a buyer from yubikey to someone here... I mean if I go buy a yubikey right now it can be used at many different sites. (using 2 factors) As long as SR doesn't make it so we have to buy the key from them, it shouldn't matter. Mt. Gox made their key so you have to buy it from them and it only works on their site. If you get a regular yubikey from yubico (which Im going to do now) it can be used with trucrypt. That would be nice to not have to remember the passphrase and just touch a yubikey...
