Don't play the what-if game.  It's a worthless excersize.  Anything
could fail and screw up the line.  The entire telco infrastructure is
scary when you dig into it.  So you are across the street, that cable
is ancient and more likley to fail than new cable from a remote DSLAM
in a hut fed with new fiber.  It's not like a T1 is more than 2 pair of
the same stuff DSL runs on.  It can all fail.  It's just usually a lot
faster to get a T1 fixed than a DSL line.  You get what you get with
DSL, it's unpreictable nature is one of the big negatives with it.  But
once you have it, it's damn stable.

None of that does anything to discount from the avaliable bandwidth.
There are shared links, but each user is limited to such a small
portion of those links, that they can't effect the overall network
enough to cause problems.  Add to that the economy of scale and 2000
1mbit DSL customers on a ATM DS3 ends up being tons of BW to spare.
