I'll send him a note and ask if he'll come along and clarify.
Does sound like something you might ask commercial systems to do, perhaps a better idea would be to have a series of small case studies for different types of sites - community or commercial, small or large, etc. Then the people who implemented the sites would do the work, get some recognition, and give the platform some publicity too.
It could even be a kind of competition on each one to put forward their best three implementations, or three which show the diversity of usage. I find showing blank installs not very effective - always good to show sites in context, gets peoples minds working...
Any other suggestions? (nice ones please :)
