If somebody's idea of 'good' gets >>75% is that a problem?
If 'best' gets <75% the there will be no progress.
Personally my feeling is that EPON doesn't belong in dot3. I expressed my
views in an email after the LA interim. I have abstained on all dot3 votes
regarding EPON since then, and I will continue to do so. I can't help
thinking that the EPON group made a rod for it's own back by manacling
itself with the constraints of dot3. The decision to spin security out was a
good one imho.
Good luck with resolution of the last few technical issue ......
btw - the only reason this is a 'reply' to Bruce's email is that his was the
most recent of the thread in my in-box. I did read the whole thread.

We can continue the debate in Vancouver but I think different groups have
different views of "the best" and Tom is aiming to get something that is
"good."
