You may have seen Vinton Cerf's comments regarding wikis. Cerf's helped many institutions along the way (Stanford University, DARPA, NASA JPL, Google) with innovative applications of technology.
From a Government Computer News interview "GCN: How could government agencies make better use of the Internet? Have you seen any Internet-based applications from a government agency that really impressed you?
Cerf: The Geological Survey has worked to index a great deal of its data, and that makes it quite useful for a variety of applications. ... I think information sharing might be facilitated among government agencies through the use of Internet technology. Whether this information is available to the public will depend on the data. Rapid deployment of Internet services can also be helpful in disaster recovery. Wiki techniques might be very useful for interagency cooperative work."
