MZnet : mail service for personal micro-computer systems

Traditional computer mail systems involve a co-resident User Agent (UA) and Mail Transfer System (MTS) on a time-shared host computer which may be connected to other hosts ina network, with new mail posted or delivered directly through co-resident mail-slot programs. To introduce personal micro-computers (PCs) into this environment requires modification of the traditional mail system architecture. To this end, the MZnet project uses a split-slot model, placing UA programs on the PCs while leaving MTA programs on a mail relay host which can provide authentication and buffering. The split-slot arrangement might be viewed as a new protocol level which operates somewhere between the currently defined MTS-MTS and UA-UA levels

draft The Green Commerce Model October, 1994 The Green Commerce Model

This memo defines a "Green Model" for information commerce using the Internet. In this model, the information merchant carries all risk of non-payment. By shifting the risk of non-payment, we do not require guarantees of credit worthiness for a merchant. This allows every participant to be both a buyer and a merchant of information on the Internet. Transactions relating to accounting and settlement are performed through either the exchange of store-and-forward messages (using the "application/green-commerce" format defined in [1]), or interactive protocol exchanges (using the "Simple Green Commerce Protocol" defined in [2]).
