	Nothing is a good enough stop-gap while things continue to grow at
this rate.  Encouraging people to throw an extra hamster onto the wheel
does not solve the problem for long at all, and encourages more waste of
existing resources.

	CIDR was only meant to buy time.  We've bought our time, and we
still don't have a solution.  If it were that easy, people would be doing
it.  Buying more time in small increments is not necessarily in our 

	Continuing to pile announcements onto this mess, looking for the
prefix that breaks the camel's back, is not a good idea until you -have-
a solution.

	Precisely -- and this /doesn't work/ if you make the existing problem
worse during those intervening 5 years.
