That's a pretty cool idea. A web-of-trust problem would have to be solved: the various systems that connect to the system would need to trust each other's internal reputation systems. You'd have to prevent people from inflating their total reputation by using a single site with an easy-to-game reputation system. Some interesting challenges in there :)
Doing something like this, you could act as a sort of social network background check, as users would not even need to opt-in to your service, they would automatically be signed up when they join the various sites.
