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.
