I'm sending this information cause I received a mail requesting some information about PCRoute, but I lost the address of that person. I hope he read this.
PCRoute is a public domain software (at the moment I don't remember the node from which I got it), runs on PC's with a localtalk card and an ethernet card. The main problem I see with this product is that does not provide the KIP protocol in order to assign and IP address to the Macintoshes that connect with it.
