Code is available at: http://code.google.com/p/nukethemfromorbit/source/browse/#svn/trunk/PasswordStrength
It's just the method for determining the strength, any UI accouterments is an exercise left up to the reader... although I'll probably make my stuff available once I have it cleaned up. If anyone has suggestions for improvement of the algorithm, please let me know.
