Under Linux, theres a network capability that can be enabled for a
program to allow raw packet access w/o having to be root. However,
it's not very useful for Python apps, since that capability would have
to be set for the Python interpreter executable (e.g. /usr/bin/python).
I avoid Windows as much as possible, but in recent years, colleagues
who do work with Windows have had to convert all of our applicatoins
which used to use raw packets to use UDP instead. I'm told that
recent windows versions have made raw packet access from userspace
(even by admin apps) virtually impossible.
