Continuous 10% packet loss does need to be fixed. But the nature of 
Internet traffic is such that it can *NOT* be eliminated. There will 
always be bursts of packet loss like this no matter what the architecture.
This may change if and when the nature of Internet traffic changes but 
for now that is a given.

In fact, it was on the NANOG list here that Sean and somebody else 
recently discussed Sprint's and MCI's plans to add many two-way 
interchange points between their networks to take some load off the NAPS 
because the NAP architecture just wasn't working out in practice.

In other words, the problem is known, has been publicly acknowledged, a 
solution has been discussed and NSP's have publicly announced that they 
are deploying that solution. Seems fine to me.

Correct terminology means everything doesn't it? ;-)

And some of us do appreciate your hard work and do understand that you 
don't have any magic wands to wave.
