Certainly IEEE needs to debate these points.
Here are some comments.

I don't think it is reasonable to couple the market we are addressing and
the low level technology used to address that market. The objectives need
to state the market not the technology.

True it does fall outside the traditional market space. Never the less may
firms are building Ethernet solutions for WAN deployment. With this area
becoming a major new market for Ethernet I believe we can not ignore it.

The links for WAN access are MAN links and therefore in the carter of
LAN/MAN. I don't want some other standards body defining Ethernet. That
would be putting the future of Ethernet outside of the IEEE. I believe the
issues is the creation of a well defined demarcation point between MAN and

It will take some education for IEEE to gain the expertise needed. I
believe we already have a start at learning some new technologies.

I would suggest we reframe from drawing any conclusions about cost or
complexity without grounded technical presentation and arguments.
