Don't be so pessimistic.  It will happen, because all the major players
want to be first and biggest to score the "triple play" -- delivery of
phone, internet and media to the household.  Because data is delivered
in bursts -- it isn't enough to deliver a movie at playing speed (on
umpty channels they need to be able to deliver a MOVIE that you can
watch or not watch until later in a few seconds -- they'll get to
gigabits to the household in -- at a guess, three to five more years
(anybody with better numbers?).  At least in some cities, towns, venues.

They're running fiber down the country road that leads past my
neighborhood as I type this -- I've been watching them bury fiber
throughout Durham for the last three or four years.  The phone company
isn't even bothering to upgrade its DSL equipment (which is totally
obsolete) because I'm pretty sure that they're never going to replace
it.  It won't happen all at once because it is expensive, it may make a
stop or two at 1.5 Mbps or 45 Mbps along the way, but it won't be that
long now.  As you say, once the fiber is there (even if it isn't all the
way to "the household") there isn't much point in being stingy.

No, I think that they'll have fiber running to households in decent
numbers starting in maybe 2010.  And whoever gets there first "wins".
