On a Wave related front
In the Republican debate the topic of a "tamper proof" biometrics based immigrant ID card came up. Most of the candidates were in favor of ID-ing immigrants, but it was Ron Paul that said if you do that, you will have to ID anyone who looks like an illegal immigrant, which puts us on the path to a federal ID card for everyone. Paul said that is a step of which we should be wary. Of course, he is worried about the degree of power that would give the government over us. So, the issues that you speak of emerge from time to time in our political debates.
On the plus side for Wave, the idea was largely endorsed by all the Republican candidates, Paul excepted. I have to believe that eventually any such ID card would involve a TPM based protection from tampering, especially since the government is beginning to require TPM encryption.
