I 2nd this. If there could be any change as to how it worked on the JR4 side, I'd say make it a subscribable feature. Meaning, if they subscribe to our site, the ad manager becomes available to them. Then they can upload ad images, which rotate on the site.
You can essentially have a separate quota for people who want to "buy" ad space.
I also had a customization on my old JR4 site that would also send a monthly email the ad manager statistics (impressions & clicks) to the email on the account. That was pretty neat I think Paul did that for me. What he did was create a separate field where I (site admin) would enter the profile ID and email next to the ad. So essentially people would pay me, then I would setup their ads (manually upload images, links, profile ID, email, etc), and they would be off and running.
If this was improved upon and more automated than the JR4 version I'd definitely buy this.
