This is an ongoing problem I have with clients, too. They get very wrapped up in whether or not the color red I used for an H1 should be "more purpley" or perhaps "more brick-y" -- when what I actually want them to tell me is if the navigation structure and content flow is satisfactory. For comparison sake, have you seen ProtoShare? Looks like a similar concept, but I haven't investigated in depth yet. http://www.protoshare.com Thanks for the review and the link, I will definitely check it out.
