Which give me another idea.  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?
