Personally I would view a password-based authentication scheme that assumes the shared key is a low-entropy one or is selected from a limited set of keys, like a dictionary, as more useful to the real world. I believe that is the predominant access method used in the Internet today. IEEE P1363.2 has a draft out describing password-based authentication protocols using elliptic curves. While a password-based authentication scheme would be _more_ useful I still think there's value in pursuing a PSK-based scheme using elliptic curves. It's an efficient alternative to the existing PSK cipher suites that use groups based on exponentiation modulus a large prime.
