AffiliateSensor

AffiliateSensor (http://www.affiliatesensor.com/)
AffiliateSensor has highly customizable ad blocks, which you can make for yourself with an easy to use on-line interface. You also get realtime reporting with clicks-by-domain, page and refferer. There's integration with Google AdSense as well, through the google_alternate_ad_url so AffiliateSensor can be used as a substitute for Google PSA's (Public Service Ads).
