If the ads were targeted to the content on the page (remember when that was top-of-the-line tech?) rather than 3rd-party ads relevant to my assumed demographic, that'd solve for (c) nicely. I wonder if (d) could be a business idea - broker ads just like a regular ad network, but have the site itself host/deliver the ads. CPM is out due to needing to trust the site with accurate reporting, but you could definitely do CPC this way and have the click targets be centralized for the click tracking/redirect part.
