So are you saying that an ipng that came out in, say, 2000 which was 
according to you was vastly superior having taken the time to get it 
right would have had any better chance of being adopted? My experience 
with Cisco product managers at the time is that they couldn't give a 
shit about the technical aspects of an ipng. If their silicon forwarding 
couldn't handle it, they weren't interested unless customers were 
clamoring for it. I can't see how that negative feedback loop could have 
ever been prevented other than other ipng being done in, oh say, 1993 
when it was all still software forwarding.
