What if directory servers were used to publish a "secret port knocking handshake" for relays? This would allow relays to go unnoticed on port scans. Obviously this would not be a technique to hide tor relays, but only to hide open ports from ISPs. As long as they do not specifically target tor relay operators, this might be effective? -Martin
