I don't think so.

Google combinations of "udp port 5353" "zeroconf rfc" "zeroconf" 
"bonjour" and "rendezvous."

I have it open, but then I see the occasional Mac. I don't think Linux 
(yet) actively uses it; Windows XP does not, unless one downloads some 
software from Apple.

I think Windows addresses the same sorts of problems with uPnP.
