	If we are still asking this question when usage-based charges are
	common, we deserve what we get.  There is (almost) no reason why this
	should be a problem, given some thought to protocol design; in other
	words, the problem is in FTP, not in whatever charging scheme.
	
We GAVE that thought to the FTP design, in 1975!  Alex McKenzie came up
with the simple and elegant Restart mechanism which is in the FTP protocol.
All that is needed is for people to implement it.  File access protocols
are very useful, but they are not needed, and probably not particularly
useful, to replace FTP Restart.
