I wonder how they will determine which open source projects are included at code.gov. For instance, I contribute to a few projects that are used within government for determining the economic impacts of fiscal policy, and the code is in the public domain. I'd love for them to be included at code.gov, but I'm not sure whether they meet the criteria.
The general guidelines are in the policy [0], linked from the launch announcement [1], but each agency's CIO is responsible for the particulars at their org. If it's not a new project post-August it won't contribute to the 20% so it might not be reviewed for release without someone suggesting it specifically, I would guess.
