For funding sources for an archive activity, the obvious choices are NSA and ARPA (myself). If you propose to ARPA, there should be some R&D component to the activity. If a bidder teamed with, say, CERT, you may be able to work out the issues of availability with them, especially if you can work with them to come up with some way of distributing the result so you KNOW who you are sending it to (for example you have positive verification of their street address, say). This will likely be a condition of any govt funding of such an activity. Teresa
