If you think of POW as a possible SPAM mitigation, how does the first receiving MTA assure the next MTA in line that a message was "paid for?" Certainly the mail relay doesn't want to do new work, but the second MTA doesn't know that the first isn't a spambot.
The first MTA would exchange the received RPOW for a new one of equal value, and pass it along with the message to the next MTA in line.
Right, I'm saying that's a possible use for RPOW, other than one that's equivalent to digital cash. Sorry if my intent wasn't clear.
