I'd better append to the first posting ...

There's an amount of controversy about what proportion of Internet 
traffic P2P actually represents.  Consensus (if it can be called 
that!):  between 10% and 80%, depending on a bunch of assumptions 
about which parts of the network, what P2P is, what P2P traffic, etc.

I've emailed Andrew Odlyzko, asking if he's managed to make sense of it yet.

Cachelogic says P2P is verrrrry big:

Glasner talks that up:

Sevcik is sceptical:
http://www.bcr.com/opinion/next_generation_networks/peer-to-peer_traffic_internet_myth_born_20051101647.htm
"My review of the data in Odlyzko's presentation indicates that 
peer-to-peer represented 10 to 20 percent of the traffic handled. 
This is the same year that CacheLogic started to see 60 percent 
peer-to-peer traffic"

Telegeography (undated):
http://www.telegeography.com/ee/free_resources/reports/gig/gig_exec_sum.php
says "On some backbones, peer-to-peer (P2P) file sharing accounts for 
a huge proportion of traffic, while on others P2P plays little role 
at all. One thing is clear-at least for now, Web traffic still 
accounts for the largest share of traffic on most networks"

Gong discusses recognition techniques:

Yang et al. provide an analysis (which I've not examined yet):
