 CHANGE> [Cox changed vote from REVIEWING to NOOP]
 Cox> So I asked some kernel guys about this - it's not considered
   an issue.  There are several other ways to identify Linux on
   the wire and people who care about this kind of thing rewrite
   their packets in various ways via firewall technology to trick
   the identifier programs.
