If you want to be the gravatar of badges, you need to make it just as quick and easy to implement.
To that end, you should have your partnering system working as soon as possible. Ideally, it should be as easy as clicking "become a partner" and copy + pasting some simple parametric URLs into your app (or something of that nature). Show someone how easy they can implement badges in less than 5 minutes.
I also agree with one of the other posts here, you should take reputation system management workload off the shoulders of your partners. Right now someone else does all the work and you get the benefit. It would be nice to be able to ping your system every time a user does one action towards the goal of some given goal.
Starts to sound a lot like conversions and goals in Google Analytics, doesn't it?
