My concern is the global mean traffic stat Freenet is intended to have all nodes hub nodes... it's not strictly scale free.

This is a real issue until we fix the load imbalance that has crippled the network; this should be fixed with NGRouting... -- Matthew J Toseland - [EMAIL PROTECTED] Freenet Project Official Codemonkey - http://freenetproject.org/ ICTHUS - Nothing is impossible.
