Eric: Would love to help. But can you wait until December? That's when we are getting HPO/5... I have a 'basic' server problem. I'd like my file server to be able to say: "Sorry, your node is being serviced by TRICKLE@.... server. Please use that one.." ,based on the user's distance from one of the 'peer' servers.. I'd hate to re-invent the wheel - can someone point me to a piece of code that calculates the distance, in nodes, between any given two nodes?? Thanks, -turgut
