Dear Ian,

WAI provides guidance on involving users:

# Involving Users in Web Projects for Better, Easier Accessibility
  - <http://www.w3.org/WAI/users/involving>

# Involving Users in Evaluating Web Accessibility
  - <http://www.w3.org/WAI/eval/users>

These and other WAI resources will certainly be considered during the 
development of the evaluation methodology.
