There's an enormous amount of skill and experience in the public sector (not just feds) on accessibility. However, these folks are not being encouraged to share what they know in a structured manner. In fact, some information that should be public is being kept private, such as accessibility evaluations of products and services, and even testing protocols.
Why not open this thing to the wider public sector? Redundant testing and vendor relations is wasteful and slow. Let a11y nerds be social!
