About a month later, there was a *major* flame-fest on the IETF list due to
this message:
http://www.ietf.org/mail-archive/ietf/Current/msg11918.htmlWhat major P2P applications have included a "run over port 80" option to let
themselves through firewalls?
lots.
It's not just handwaving.
the handwaving is based on some presumption about what
is on the other side of the "port 80" spiggot.
what other services are enabled on your systems that
listen to port 80?
do you have systems that don't speak/listen on port 80?
(*) Remember - satire isn't funny if it isn't about something recognizable...
... to someone.
