I spoke with David Chaum, the inventor of digital money, last week at the cryptography meetings in DC. He is willing to give us a noncommercial license to use his digital money patents, and copies of some of his software for digital cash, for us to deploy somehow, and start using. He'll be back in August for Crypto '93 in Santa Barbara, and will bring one of his assistants (Nils) up to the Bay Area to teach us about the software. I think we can get a copy from him in the meantime, and puzzle it out ourselves between now and then. We'll also need to work out the legalese on the patents; it should be simple, but then again, almost everything *should* be simple... If we have a small group of people (say 2 to 5) who are seriously interested in building a digital-cash-on-the-Internet application and getting it into use, then speak up and get organized, and I will cross-connect you to David and Nils so things will start moving. David's company Digicash has been working on toll collection systems; he showed pictures of their newest system that allows driving full speed through the tollbooths and still does the transaction, using infrared through the windshield, I think. If someone wanted to present his system and his company to the authoritarians who were last seen preparing to put unencrypted automated vehicle-ID numbers on cars in California for toll collection, that would be a good thing. Speak up... John
