Sad as we all know the main cost for 1g to a site is in the optics
(well actually the fiber build... But after that, it costs almost
nothing to light it at 1g). A pair of 20km optics is about $250.

I see that assertion a lot, and I want to correct it.

The major cost, MRC, is *the router port*; I don't know what the 95%ile
BW for a major hotel is going to be over a month, but I suspect that
you're gonna need the whole 1Gb/s worth of port to handle the peaks.

And those aren't exactly cheap -- though, by "daily commercial hotel
revenue" standards, I suppose they're not *that* expensive; what kind
of margins do hotels make?


Actually, local loop usually exceeds router port.

If you're at one of the data centers where we have presence, I can sell you a dual-stack Gig for <$1/Mbps.

OTOH, getting a Gig-E to the datacenter from the hotel and then the additional cost of the XC are probably more than 
$1,000/month when combined. Possibly by some multiplier ≥2.

I'm not sure how you've arrived at such an assertion.  I thought
20$/mo (or even below) was more like the cost of an FTTU pipe;
lighting at dedicated GigE would probably bring it higher, but (prior
to XC) the cost should still be comparable.

Also, how about microwave links?  Webpass.net seems to have some nice
offerings for residential buildings in SF Bay; it would seem like
their technology might be perfect for the hotel sector, too.

Also, even at $2,000/month -- wouldn't this still be several times
cheaper than what they pay for newspaper delivery to every room?  Oh,
I get it, business people require their morning newspaper, but inet,
ehh -- only the kids need the internet!
