Cool idea. It would be nice if this was generic and hackable. For example, I have a mailing list, and it would be cool to see the # of users on the mailing list, or website subscribers, etc. It would need some type of API to go along with it, I'd purchase it, if the price was around ~100.

Branding, maybe just send along a pack of stickers, so if someone wants a facebook tracker, they just apply the facebook sticker, etc. Maybe just a template that people can print their own branding, etc. then you don't need to print anything on your end!
