If we could just performance tune that engine in the Smart car, then your concept might be more compelling. I wish this could be true. We would be finished with this issue now. At present, however, we have to find a new engine (improved VCSEL) and/or strap on rockets (FEC, EDC), which doesn’t seem so Smart anymore.

You know me - I like analogies; I seem to remember using airplanes as an example during the development of 10GbE, something like comparing 747s to regional jets. I also like automobiles so let give you my take on where we are at as it relates to 802.3ba.
I agree that the bulk of automobile product line only has 5 passenger capacity. However, how many cars will you see this morning on the way to work will have five people in them? Very few - most will have one and some will have two. Using the 802.3ba philosophy, we would standardize a two-seater since that is what the majority of the market needs. We would ignore the typical sedan which gives broader market coverage at maybe, just maybe a small premium. I view the XR variant as the typical sedan.
We have an objective for Scooters - 10m of copper - just get me from here to there at the lowest cost
We have an objective for a Smart car - 100m of MMF - good enough for most commuters
We have an objective for a Greyhound bus - 10km of SMF
We have an objective for a turbo-charged Greyhound bus (or a John Madden luxury liner or a 747) - 40km of SMF)
But we have ignored the family sedan that provides broader coverage at a reasonable cost. Our argument is that it is not large enough or doesn't warrant the extra cost. I see 10-20% of a lot of ports as much, much bigger than 100% of hardly any ports (albeit expensive ones). I don't hear anyone talking about how small the 40km SMF market is.
I still don't get it.

What should we tell our customers who have link lengths longer than 100m and want (or require) a standardized solution?
