Personally, I believe you won't see any useful/fast anonymous p2p
network until most users have very fast broadband connections with
high upstream (something that isn't very common in my country for
example) due to the huge amount of data that has to be forwarded or it
would be awfully slow. While broadband is catching up in many
countries to a point where it's really fast quite networks need to be
created or adapted (as you wrote). So as long as development time is
not lacking behind broadband development it's probably all on the
right track. However, I believe it will take many years still till we
are at a point where most users have the bandwidth to ensure a fast,
anonymous network. Take the edonkey network as an example. If everyone
contributes just 10-20 kb/s it might be too slow unless the file isn't
too large or you have a huge amount of uploaders. So if that is too
slow, it would take even more upstream bandwidth to send the data AND
the encryption related data / the forwarded traffic of other users as
well as your own).
Look at VoIP for example, it's just the opposite: encryption programs
such as zfone are available, so is the bandwidth in many countries.
However, hardware development is lacking behind (okay, zfone is rather
new still) and it will still take a good while until you can initiate
encrypted voip conversations with hardware phones (hopefully earlier
than later).

I remember some people came up with the idea of creating VPNs so each
user gets a different IP instead of using his own. I'm not very
experienced in VPNs but I believe that requires a VPN host/service
that guarantees to not forward the connection data to anyone and/or
doesn't log any connection data.

When looking at available anonymity services it appears as if we will
have to use different networks in the future for different purposes
because each of them seems to specialize on something. Freenet for
example seems to be perfect for storing web content anonymously (blogs
etc), I2P (never tried this yet) for p2p and Tor for browsing, IRC
etc. But who knows, maybe one of these networks will become one
network for everything someday instead. ;)

Sincerely,
Enigma
