The software uses a privileged port that is part of the firewall (of
course).  As well, there is a password required, although almost certainly
it sends the password over the local area network without encryption.
However, your point is certainly a consideration for people setting up such
systems.

I like the idea of not shutting down completely when the batteries run down,
but leaving the system in single user mode.  I will see whether it can be
done with the software set up that I have.

Thanks Matt (as always)
