	Here too.  I feel our system is rather site-specific and a little
	rough at the edges, so I'm not inclined to make an "announcement".

	Our system doesn't show occupancy per pool, but aggregates over
	each subnet prefix, as we have a number of discontiguous pools
	in any subnet larger than (prefix shorter than) /24.  So far,
	we haven't needed to block external access, so anyone can take
	a look at  If we
	find that access from outside becomes a problem, we'll block it.

	I hope to look at Trond Hasle Amundsen's code and learn something.
