Michael,

  This is the second one  of these responses I have gotten.  BTW

  I agree.

  IMHO if v6 is done properly there should be no problems security
wise.  I also believe that v4 can handle the TTL of 254 without
too much problem either.  SO the v6 concern is moot really at this
point anyway.  Time is also a factor here.

  I don't think we have 5 or 6 years for v6.  In fact 2 years is
the outside time factor at the current growing demand for routeable
IP demand.
