Following the discussion about using GNUnet for software package
distribution I started thinking about what kind of data *read access*
traces matter to people's privacy.
Map data bumped into my mind, because it's obvious that where one
zooms down and the places one searches for tell alot about ones
Thus it might be desireable for users to access map data anonymously
e.g. using GNUnet.

This sounds very useful eg. for Planet.osm distribution.
It's already available via BitTorrent
but the regions are very large and thus the files are too...

Anonymous access to local OSM data as well as (cached) rendered map
tiles would greatly improve users privacy, obviously...

I'd greatly appreciaty a discussion on how Planet.osm can make it
into GNUnet and how that API could be promoted to the application
development community.

(I'm aware that one can just use TOR to access OSM, but that would
still allow a sufficiently resourceful 3rd party to associate the
timing of TCP connections on both ends and de-anonymize TOR users)
