The non-profit built for "opening America's government" has created an app to show off its Congressional data, as well as its API (our Sunlight Labs API profile). You can't get this app on the web, though, as it's available exclusively for the Android phone platform.
The National Institue of Standards and Technology (NIST), has created created AppVet. AppVet is an open-source tool that IT groups can use to test applications for use on government networks. AppVet was designed to easily integrate with third party apps and tools (e.g. antivirus software, analyzers, vulnerability repositories, etc.) through simple APIs.
