That's a very good point.  If serveral nodes bombed
the area for a long time, it would become resistant by
growing big enough to handle the attack.  However in
the short run I'm not so certain the network can
adapt.  GB of data have to move around for the network
to adapt.  It seems like a strange race between junk
being piled in and more nodes piching in to help.  Who
wins?

Yeah, I don't know.  Freenet might be able to handle
some kind of localized rehashing among friends or
something, but it would certainly seem to muck up your
design and principle.  I just want to push the
envelope and see if there maybe something that can be
more rigorously proven to provide security.

Yeah, it looks like the routing is going to take
O(log(N)^2), if it works.  I'm still a bit stuck
though.  I'll post if I ever get anything proven to be
solid.  Basically what I'm doing may not be nessesary
or possible, but if is I'll let you know.
