      your first lema is false.
      and RTE are more scarce.

      let me ask you two questions:
              ... how many /32's are there?  

The same number as there are /32s in ipv4, also the same number as there
are AS numbers which has a certain nice congruency to it...

              ... how many of them will you allow in your routing table?

Hopefully not all of them by tomorrow.

      and a bonus question:
              ... what are your criteria for rejecting a given /32?
