They know you live there, and they don't like *you*.

the problem is that packet loss is not as cheap as with networked data...

That is, indeed, a small problem. (!)

Dream on. What you get depends on where you live. If you live in a city,
perferably in the heart of a large city, then you are right. If you happen
to live in the outskirts, no chance.
Examples from Berlin (German capital) and surrounding areas:
- Berlin outskirts, near the former Berlin wall (1 Mbit/s downstream, 128 kB
upstream)
- regular street but: street surface is sand - when it rains the area
becomes unpassable, have seen more sound streets in Egypt - at least they
were dry...
- Brieselang, 11.000 inhabitants, 15km west of Berlin
- center of town, 1 minute away from train station (3 Mbit/s downstream)
- other, more remote areas: less than 1Mbit/s
- other areas in east Germany (the areas where there are just 20 year old
glass-fibre cables available)
- ISDN available only, no ADSL (max. 2x 64 kbit/s at forbidding cost)

I guess Munich just has good support in the outskirts too. Now I live 30 km
from the centre and get 6 Mbit/s (not sure if this is the limit of my line,
my plan/modem is max 6 mbit/s). According to this map of where VDSL is
available:
http://entertain.eki.t-home.de/hilfe-und-service/verfuegbarkeit-vdsl-ausbaustatus/
most of the towns/suburbs around me have VDSL but I don't :-( It looks to
me like pretty much the entire population of Munich itself is covered by
VDSL, and a lot of the towns/villages surrounding it.
But like you say, I guess you need to live in or near a large city to get it
currently.

Out of idle curiosity: have you actually measured data-transfer?
I pay for 6Mbit/s but get only 3Mbit/s. Of course, all kinds of people want
to sell me flat rates with "up to 16 Mbit/s" - but when I ask them to give
me a written statement that I >will < be able to use at least a 6 Mbit/s
line, I never ever hear of them again.
God, how I hate advertisements with "up to" or "starting from"...
It's a bit like trying to sell a 40 year old VW beetle and advertising that
it will be able to travel at speeds >up to< 800.000 km/h...
Incindentally it actually does travel this fast provided you look at it from
the center of our galaxy. ;-) The actual speed and direction of it relative
to your own street can be seen as a mere pertubation in this case.
Everything just depends on your standpoint...
(For the more conventionally minded resellers of used cars: we can safely
assume that any car can travel at speeds of up to 200 km/h, albeit briefly.
Just push it off the cliff of your choice.)

My employer's Internet connection is *guaranteed* to be 5 Mbit/sec in
both directions at all times. (There are also contractual guarantees
about how quickly the ISP will fix it if it breaks.)
How much do you pay for your broadband?
You *can* buy guaranteed bandwidth. It's just kinda pricey... ;-)

For a sufficiently high cliff. And provided that the car's aerodynamic
drag is insignificant compared to its mass at that speed... If it's a
Robin Reliant, this is a dubious assumption.

Or as a uni lecturer said to my data comms class (circa mid 1980's):
"Never underestimate the bandwidth of a ute full of tapes speeding down
the highway"
At the time we were learning about synchronous protocols operating over
1200bps links.
