Any operator trying to control which applications are used on their
networks has either never learned, or already forgotten, the lesson
of "fsp, NASA, and OZ."
Precis: they (developers, users) can modify the application to use
spread-spectrum style port numbers that constantly change throughout
the life of a session, which makes it effectively impossible to
filter using existing technology.
Sean Doran has it right: be glad this is bulk TCP (fsp was UDP
based), and turn on RED.
