        Craig, you are right about the certification of bad transfers. Messages
        from some trusted network component might satisfy such a
        requirement. I know this sounds messy, but even the telephone
        system sort of relys upon my work to say the a call was disconnected
        during use and I get a full refund, even if I only call back and say
        goodbye and pay only the minimum charge. Such are the issues
        of charging for useage.

Dennis,

The solution is to implement the FTP protocol, including FTP Restart! The
user DID transfer most of the bytes... why should we return his money?
Why create a hard problem when there is a trivial solution?
