                      <pre>Hi John,

That's incorrect and obviously so. While repurposing 240/4 as general
purpose Internet addresses might require that level of effort, other
uses such as local LAN addressing would only require the equipment on
that one lan to be updated -- a much more attainable goal.

Reallocating 240/4 as unpurposed unicast address space would allow
some standards-compliant uses to become practical before others. A few
quite quickly.

                      <pre>Is it not past time we admit that we have no real idea what the
schedule or level of effort will be for making IPv6 ubiquitous? This
year it was more than last year and next year it'll probably be more
than this year. The more precise predictions all seem to have fallen
flat.
