Post your idea on how a toolbar can be monetized. I will give you thanks. Background: I've stumbled on a very hungry, low competition niche, and have decided that the best way to attack this niche is with my very own toolbar. The tool bar will solve the problem of this niche but then the question becomes, How Do I Make Money With The Toolbar????? I remember hearing about this really blackhat toolbar that would replace all Google Adsense blocks on all sites with the creator's own adsense blocks. It would be awesome if it still worked, but I'm pretty sure I'd get banned within a week doing that. Then I also thought what if my toolbar tracked their website history and I served up little pop up windows from time to time (not frequently enough to make them get rid of the toolbar) which was tailored towards what they are looking for. That would be a LOT of work however, and I like easy money vs hard money.
