That way new node #s get picked up. Hadn't thought of that, but I like it. Reminds me of ARP in a way. Instead of each node maintaining a map of the entire network, what if it just maintained the number for its successor? Then handle gaps as you mentioned above. The last node will have to remember the first node as its successor. Also, it would be nice for a node to send its new successor the number of its old successor. -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
