How to leverage reputation systems of other communities to encourage participation in your own

Question

I am developing a community from scratch whose target audience typically frequents several other communities and utilizes different collaboration tools, each of which has its own activity or reputation profile.

My goal for my community is to encourage cross community collaboration, which to me seems like I should leverage the reputation and activity profiles of these different tools, rather than only create a separate gamification system.

Are there good examples out there of communities that do leverage reputation or gamification systems of established third party communities. How would one develop a community platform feature that would implement such a capability?

Specifically in my case: I'm working on developing a professional community that links multiple open source software development projects. Each of these projects has its own collaboration mechanism. Like many projects, they use a combination of GitHub, Jira, Stack Overflow for primary collaboration. A mix of forum or newsgroup software is used - anything from Google Groups to mail list managers.

What is a way to allow my community members to show and add to their professional reputation in these other established communities?

Coderwall is somewhat close to to the experience I'm looking for. What I like is that it allows you to link your GitHub profile, where contributors to open source software projects have their statistics and contributions displayed. It also allows one to connect LinkedIn and Twitter. The former adds some professional reputation, and the latter is just social media. What it lacks is a connection to Stack Overflow, which is also an important reputation source for engineers. However this is less a "community profile" or service, and more of a recruitment oriented social site for developers.

@zerotime suggested Geeklist or Masterbranch. Masterbrach is closest in terms of linking multiple communities together in a conglomerate reputation. However that seems to be where they end - making the composite profile. I'm looking for examples who's using a capability like this to drive engagement across multiple communities.

The only answer I can think of is Klout's effort to integrate reputations across social platforms. Lithium bought them recently and is integrating it into their existing community platform, although so far that just means you can see someone's Klout score on their profile.

edit: So Klout has been around for a while. They attempt to merge all of your scores on various social platforms, such as LinkedIn, Twitter, Facebook, etc. They give you one single number which determines their estimation of your reach and influence. To you as a consumer, you'll get "perks" from vendors who want you to mention their products online, hopefully. Lithium bought them a couple years ago and is incorporating the Klout score into their community platform and social monitoring tool. They're also hoping to expand Klout to products as a centralized review tool like Bazarrevoice
