In what I quickly proposed, nodes would send netnews by a push method but clients would download news with a pull method. The reason for have nodes use push instead of the normal pull would be due to the fact that not all nodes would have netnews over Freenet support. Those that did not support netnews over Freenet (either because the server itself doesn't know about netnews over Freenet or that the system administrator has turned off support for netnews over Freenet - giving the option is a good thing because netnews can easily swamp machines which don't have large quantites of hard drive space available) would just pass on the push messages without interpreting them. Of course, pull would be favorable - provided that nodes aren't just smart enough to pass on unsupported messages, but to also pass back replies to unsupported messages. In that case, I would have to support all pull instead of node-node push and client-node pull. However, I don't know whether they have support for this, and if they don't, server-server communication will have to be push. -- Travis Bemann Sendmail is still screwed up on my box.
