Our agency, the Defense Contract Management Agency (DCMA), does allow access to most Google Apps currently online. However, I believe we will never utilize them for fear of security. Because we fall under DoD, there is a heightened sense of keeping information secure and behind the .mil infrastructure. In addition, we contract out to random companies to develop online, portal solutions for us to share data and communication. The problem is that rarely do the products contracted for actually meet the needs of the workforce in the field, as well as being very non-user friendly. We hear rumors that we're going to MS SharePoint, but that's also a dream as far as I'm concerned. It would be great to go to google apps, but I think it's an idea that will come and go here at DCMA.
