My suggestion: don't attempt to mix security into each individual
application in a piecemeal manner. Use the proper tools for the
job, such as firewalls. Setting up a firewall on Linux or WinXP
is nearly trivial at this point, and the learning experience is
worth the effort for those who are new to this, so there's not
much excuse for doing it properly, IMHO.
