I suspect the benefits will be massively outweighed by the gains, as far as routing and specialization are concerned - new nodes need more data fast, so that they can get serving, for example. Once the store is full not only we CAN select what to cache, we HAVE TO. I think we can solve the anonymity issues by other means, see my other messages. -- Matthew J Toseland - [EMAIL PROTECTED] Freenet Project Official Codemonkey - http://freenetproject.org/ ICTHUS - Nothing is impossible.
