So, add the code to mixmaster (and even the old style remailers) to collect e-cash as it passes on the anonymous message. Then this will be a good way to accumulate some e-cash, and a number of people will try running remailers for this very purpose. Witness the recent Usenet spam by someone advertizing a for-pay remailer.
I was invited to the digicash API design meeting precisely to make sure it could be used in remailers. It will not be using the current API. The problem is that Mixmaster requires exact knowledge of the size of every object in the message, to maintain constant message size. I could set aside room for one, two, three coins, but there is no guarantee that the payment will be made with only that many coins. The current API is going to be high level. It will does not allow the program to know anything about the internals of the payment. I need to be able to specify payment of amount X using no more than N coins. As soon as I have that level of control, you will see postage in Mixmaster. -Lance -----BEGIN PGP SIGNATURE----- Version: 2.6.2 iQEVAwUBMZ40x/Pzr81BVjMVAQFdTQf/VtRl3MEm+YfIYxsJdEhnv9lsL26S00oG RTvJiVbzyriGmWBhQY14ITQjnPrNNnRYfrmxVT2nRAEpfC8a63TqD5BN2eeUOSWU g/eagI3mWqlQssjCpeOEq6pzBcvKCTu2nECfAWCVN87MA7thq4Xj3haFjv+NP2K6 i8Bq/JRz6oaq35Bz0lqskBemiUOLXJOUK93LXFpw3VlTces+vDMSCWXwtkhAOLLO yav12MbRJRt/heUotsl6wzp2tdEV4xlsciedUOfk8fQVDSvh31J2xyvaupepHosC UUCz3sc8f4icWXCtBkimLyzgp/pNg7E9rN//Ps8ZzQquKPcr/7GtAQ== =BC1f -----END PGP SIGNATURE----- ---------------------------------------------------------- Lance Cottrell loki@obscura.com PGP 2.6 key available by finger or server.

I mentioned this to Chaum, and he didn't really seem agree with the need for something lower-level... Another problem with postage in Mixmaster: the minimum ecash payment is $0.01. Do we want to charge that much for email? Need we consider micropayments? - Ian -----BEGIN PGP SIGNATURE----- Version: 2.6.2 iQCVAwUBMaCeeUZRiTErSPb1AQE4AgP+NvB6MjqSeF74NEeakj+u+99oZwBcFHuP ESwbu/QiRiiolU8beC341p0HL40KHdCyfx7rfQUDOIAXzGnLaoBCjVSw/DotAlAD UuB6NI9TXhv7j5dIywOdyYAp6SU10IKDLEuA6lkQ+jg71fXteoFF0o2nTpGaPcaU Zqv9/UZmglI= =1Ffr -----END PGP SIGNATURE-----

The above, as stated, is inaccurate.
