I'd always go for over supply of bandwidth, but your always going to run
in the last mile provisioning of bandwidth, which is where telco's still
rule, that's why stuff like consume.net really intrests me, a great way
of utilising cheap(free) bandwidth in small local area's to provision
bandwidth (if a tad unreliable ;-) ).

Err, I'm sure the big boys will get there army monkeys with typewriters
to come up with some plan, we'll be paying for it of course, look at
global crossing, lots of suits, lots of promises, blind investers with
lots of IP acronyms and just buy buy buy cisco..can't go wrong can
you??? well not if everyone so corrupt they look like a harddisk after a
head crash.

ha ha, when I first read about BGP routing, my first though was, how
does this ever work, then I looked around for bgp horror stories, there
are many, funny thing is smaller ISP and hobbiest seem to get it right
and *understand* bgp, it seems the monkeys in suits with typewriters
seem to foul it up most of the time, not that they care, they can always
zoom of in the jeep and go down the golf course, via the exclusive heath
club safe in the notion that there telco gives 'excellent packages for
droid like behaviour'. ;-)
I really like ISP provision when it was small, no big business has got
invloved, they seem to be taking the service out of ISP. Broadband, what
a sham that is, no matter what you do, you just can't avoid bt ATM
network, so what ever services are ever offered, it's going to be
restricted to the living dinosaur network all ISP depends on, BT, ooohh,
love em or hate em, you can't avoid em!!!
I have to be rather

I be cynical about anything involving the internet that needs expert
administration and trust, because rarely do you find experts or any kind
of trust involved with big business.
darn it, I've done it again, gone from technical to politics...must stop
that....must stop it!!! ;-).
OUCH!....
