The namespace actually contains nothing but a pointer to the
directory. The directory and its contents are immutable,
and 'certified' transitively. If you wish to allow an user
to download something from the bottom of a directory hierarchy
without descending the hierarchy, you need to provide the
user with the AFS URI of the file, instead of its path.

Bittorrent is probably your best choice for that currently.

We already have scripts that transmit perfectly good and
honest /dev/rand data around. With a few nodes running
those, I suspect GNUnet has about the same
good_traffic/(good_traffic+naughty_traffic)
-ratio as the internet has.
