What I tried to convey is that any report on this subject needs to
be transparant as to who or what paid for it. The report you linked
to on Quintarelli's blog is a positive example, as all the logo's of the
European duopoly are under it.
One finds honest as well as self serving arguments in this discourse,
it is my experience that 'spontaneous' reports by scientific institutes
often indicate the latter.
I agree at once with you that there's nothing wrong with paying a
normal price for a good network with good service (disclosure: my
30/30 Mb Amsterdam FttH costs me euro 59 a month).
As for Japan Kenjiro Cho et al. very recently published (Oct. 16)
excellent new research showing that the percentage of bandwidth
used for P2P in Japan is still high, however decreasing:

Earlier research by Cho et al. (2005) showed that yes, it is a small
percentage of users that are 'heavy hitters' (i.e. P2P et.), however
over time most users for a short time will belong to that small
percentage.
In other words a usage pattern comparable to that of many other
infrastructures. In June '08 Barabasi (the author of 'Linked') published
research on traffic patterns based on 100,000 followed EU cell phones.
Conclusions:
- 46% of all cell phone owners never leave home more than 6 miles
- only 17% of people travel regularly beyond 37 miles
- only a third of the above (6% of all) beyond 124 miles.

So together we pay for a long distance travel infrastructure i.e. highways,
railroads (these are European cell phones), without having cui bono
debates. Of course it helps that about 100% of the people want to keep
the option value of the fast long distance travel, like for annual holidays.
Last, back to Japan and broadband, the same Kenjiro Cho in May this year
pointed to a guideline for packet shaping released by the Japan Internet
Providers Association (JAIPA).
Kenjiro quotes from the guideline:
"Basic Concept
Because of the rapid increase in Internet traffic, ISPs, etc. that
either already implement or are considering implementing packet
shaping are on the increase. However, it would not be appropriate for
ISPs, etc. to easily implement packet shaping beyond a reasonable
threshold for the purpose of averting network congestion when it
should be tackled by enhancing network capacity. In the first place,
ISPs, etc. should tackle the increase in traffic by enhancing its
network capacity. It is important to recognize that packet shaping
should be implemented only in exceptional circumstances, and to share
this basic principle as a consensus among telecommunication carriers."

Everyone:
Ad hominem arguments against the publishers of the reports mentioned in this thread do not affect their validity. And valid they are.... As I, as an ISP, can attest, policies which prohibit network management and optimization would indeed raise our costs substantially. In fact, even if we invested much more money in expensive infrastructure and backbone bandwidth (which is especially dear in our area), we would still likely fail to maintain good quality of service. Why? Because -- as experience in Japan has shown -- the appetite of P2P for bandwidth is essentially insatiable. What's more, longstanding flaws in the TCP/IP protocol suite allow applications such as BitTorrent to seize priority over time-critical traffic, causing jitter on VoIP calls and annoying pauses in streaming video.
Who benefits if network engineers are allowed to do their jobs, network designers are allowed to innovate and broadband providers are allowed to compete on the basis of the quality of their customers' experience? Everyone... except for the bandwidth hogs and pirates.
