I just started a community wiki with the same idea but inverted; it's a catalog of known successful startups and their business models: http://bizmodels.wikidot.com/ http://bizmodels.wikidot.com/ So it starts with the examples instead of starting with the business models. Maybe a catalog as you wish could be accomplished tagging the corresponding startup wiki pages with "ad-supported", "freemium", "license software", etc., and then navigating each tag to find examples. Feel free to modify the wiki to enter wiki pages for business models themselves.
