The DNSSEC-Tools project is undertaking a studying to determine how ready the world is for deploying DNSSEC up to user applications, and they've created [dnssec-check], a utility you run on your network and (if you want to) submit the results back to the project.

The program examines the system's configured resolvers and performs a number of tests, lighting up lights as it goes. Download the program as source or binary for Mac OS/X and see what your environment looks like.
