Many things aren't as obvious as you state above.  Take for example routing 
table growth.  There's going to be a big boom in selling routers (or turning 
off full routes) when folks devices melt at 512k routes in the coming years.  
Operating a router takes a lot of things, including power, space, people to 
rack it, swap failing or failed hardware, OPEX to the vendor to cover support 
contract (assuming you have one), fiber cleaning kits, new patch cables, 
optics, etc.

These costs are variable per city and location as space/power can be different. 
 This doesn't include telecom costs, which may be up/down depending on if you 
are using leased/dark/IRU or other services.

Building fiber, data centers, can be quite capital expensive.  Fiber, expect 
50-100k per mile (for example).  It can be even more depending on the market 
and situation.  Much of that cost is in the labor to the technicians as well as 
local permits as opposed to what the fiber actually costs.

Many people have fiber they built 10 years ago, or even older.  Folks like AT&T 
have been breathing life into their copper plant that was built over the past 
100 years.  Having that existing right-of-way makes permit costs lower, or 
allows you to get a blanket permit for entire cities/counties in cases.

Some cable company has a presentation out there (maybe it was at a cable labs 
conference, or otherwise) I saw about average breaks per year.  This costs 
splicing crews that you either have to pay to be on call or outsource to a 
contract company for emergency restoration.   

http://www.southern-telecom.com/AFL%20Reliability.pdf has some details about 
these.

There was a presentation by Vijay about the costs of customer support.  Many 
states have minimum wages higher than the federal minimum wage, but even that 
being said, you need to pay someone, train them, give them a computer, manager, 
phone and other guidance to provide support for billing, customer retention and 
sales.

I recall Vijay saying that if a customer phoned for support it wiped out the 
entire profit from the customer for the lifetime of them being a customer.  
That may not still be the case, but there are costs each time you provide a 
staff person to answer that phone.  Sometimes it's due to outage, sometimes 
it's PBKAC, sometimes you don't know and have to further research the issue.

Your overhead costs may be much higher due to the type of other costs you bear 
(pension, union contracts, etc..) vs a competitor that doesn't have that same 
structure.  This is often seen in the airline industry.

I for one would like to see more competition in the last mile in the US, but I 
think the only people that will do it will be folks like sonic.net, google and 
other smaller independent telcos.

Take someone like Allband Communications in Michigan.  They brought POTS 
service (just recently) to locations that Verizon/AT&T were unwilling to build. 
 The person who wanted the phone service ended up having to start a telco to 
get POTS service there.  They just went triple-play since it was the same cost 
to trench fiber as to put in the copper.
