You have forgotten here, Bill (I am feeling charitable, so I will not add
... no, I said I wouldn't add it) "MRC".  Unlike some things for which 
bonds would be floated, this sort of service *would be being charged
to someone, every month*.  

Sure, you won't get 100% take, but we factor that in.

And, the number of times it's been said notwithstanding, I think 
a resaonably defensible case can be made that consumer services are
pretty close to as good as they need to be at this point; for the 
*average* consumer, you're pretty hard pressed to run out of space
on GigE downhill; uphill even moreso.  Sure, there are edge cases,
but we call them that for a reason.

Stipulated.

Was there an argument there?

That sounds like an argument in *favor* of the Muni providing backstop
service at L2, rather than the position against I thought you took.

Ah.  Then we *are* singing the same song, or most of it.

Hmmm.  This isn't the view I'd been getting from you on this, I don't 
believe.
