[Zope] DoD Users That You Know Of?

I am considering application of Zope to a Department of Defense (DoD) customer. It would be very helpful to talk with other DoD type users of Zope so we can establish to other DoD people that the product's already successfully in use. Can you give me contact information on any such users please? v.r ......Andy K. (719) 637-7324 and awkraska@tasc.com
