The concept of a unified authentication scheme based on biometrics is interesting, but may be fatally flawed.
Apart from technological issues, a significant problem may arise when any of your identifiers are compromised. With passwords, you can just select new ones and continue, but you can't change your fingerprint, for example. This may lead to a scenario where a whole trust system is blown away.
To do anything really useful in the long-term, we need to proceed with caution and be extremely mindful of concerns about personal freedoms, etc. At the moment, I'm happy remembering secrets and would not feel comfortable using biometric-based systems where I cannot trust every part of the authentication network.
