Usually routed messages/queries isn't what should consume most of your bandwidth.

I would do it, especially if I didn't need all that bw all the time for something else. Also consider that your node will become better at locating data the more you allow other people to use it (given that routing works as supposed). > [1] This is some assumption.

Again, freenet nodes doesn't talk to each other using HTTP. /N _______________________________________________ Support mailing list [EMAIL PROTECTED] http://news.gmane.org/gmane.network.freenet.support
