That's also a worthy goal, but it doesn't address the issues that
are the subject of this conversation. Middle-mile solutions
like this are not all that uncommon, even in such backwards
places (when it comes to networking infrastructure) as silicon
valley.

Where we still have a serious lack of deployment and virtually no
competition, even in most major metros, is the last mile.

This is definitely a good first step if you can get it through the legislative
process without having the $TELCOS and $CABLECOS lobby against
it to the point of death or dismemberment.

Sounds great... Now, the $50,000,000 question... How do we replicate
that model at the consumer level?

That's certainly the ideal, yes.

There are cases where the lack of L2 services could pose a barrier
to entry for competition. That's why I proposed the following requirements:

1.	Must sell dark fiber to any purchaser.
2.	Must sell dark fiber to all purchasers on equal terms.
	(There must be a published price list and there cannot be deviations
	from that price list. If the price list is modified, existing customers
	receive the new pricing at the beginning of their next billing cycle.)
3.	May provide value-added L2 services 
4.	If L2 services are provided, they are also subject to rule 2.
5.	May not sell L3 or higher level services.
6.	May not hold ownership or build any form of alliance or affiliation with
	a provider of L3 or higher level services.
