Well, I just did a default install of freenet and I
see that the defualt store size is still only 256MiB. 
Right now the network is seriously overloaded and
bandwidth is scarce; tiny data stores compound the
problem.  If you have a good reason for such a tiny
default datastore size, I'd love to hear it.  The
second area, is bandwidth limiting.  Right now, I
notice that my node, even though it has >20MB or data
wating to be sent, the upstream bitrate varies from
about 1/2 to 3/4 of the vaule of my upstream bandwidth
limit.  If 3/4 of the limit is the maximum, then why
doesn't my node send data at a constant rate at the
maximum bandwidth limit specified?  I turned off
bandwidth limiting and the node transmitted at the
limit of my upstream speed and stayed there without
slowing down even slightly.  Optimizations in the
bandwidth limiting would help maximize the performance
of the network.

One other thing, I read on article in Scientific
American (May 2003, pages 60-69)about scale-free
networks that was quite interesting.  Intuitively, it
seems that freenet is a type of scale-free network
itself.  One of the weaknesses of these types of
networks is that they are vulnerable to attacks on hub
nodes.  My concern is the global mean traffic stat
that is associated with each node.  An attacker could
gather information about the network and use these
statistics to identify the hub nodes in the network. 
The attacker would then have a better chance of
disrupting the network by focusing an attack on this
subset of nodes.  How likely is this?  Is it a concern
for the developers?
