That's a very good characterization of the issue. (I wish I could be
that accurate and concise.)
In terms of when one hits the wall on #1, Frank Solensky of FTP Software
has been doing projections for a couple of years regarding when address
space prefixes run out. And he's projecting a very long time (the year
2015 sticks in my mind) for exhausion of classic class b and c chunks. His
last projection is perhaps a close to a year out of date. (One would hope
that ipv6 or nat would be more widely deployed by then ;-)
Are other people coming up with more conservative (i.e. exhaustion occurs
sooner) estimates? If so, and if exhaustion is projected by the millenium
or thereabouts, then my premise would be incorrect.
