as i said privately to someone, a few problems
  o the scale of destinations is far to large.
  o how are you to know what is an important host inside of a
    complex enterprise?  the granularity of routing/filtering
    within sites is not externally visible.
  o many of a large complex enterprise's sources from which it may
    be desirable to test may be in 1918 space.
  o the pingees may not like being pinged.

the goal here was for isps and enterprises who want to be good
citizens to be able to test.
