None Re: Remailers and ecash

Another potential scenario is to assume that a.a.m is going to continue to grow until it becomes unwieldy. Then people will have to pay someone to store-and-forward the messages, or split it into smaller pools for which people can provide their own support by running small news servers on their machines.

This is exactly what is happening. In fact one ISP mentioned recently on this list keeps alt.anonymous.messages traffic for an extended period of time for their customers. On a more practical note, if the user downloads all the messages, or uses secret-sharing techniques, the ISP can sell accounts using non-anonymous payment methods and not know which users are receiving which messages. No blind ecash needed.
