Interesting, thank you for the insight and some detailed breakdown.  I'm
actually really glad someone with some more experience jumped in with
some actual background in this effort.

One thing that cropped up in my mind from the late 90s and AFAIK still
goes on today - isn't it pretty well documented that more then a small
number of 'professional' firewalls have a habit of just outright
discarding/rejecting/barfing on packets with options in them that they
don't recognize?

IE: PMTU/ECN blackhole redux.

Of course since IPx1 requires some stack upgrades, so that point is moot

Sigh.  Back to the original thought that its just easier to go IPv6 then
try to 'fix' whats already out there.
