I guess the simplest and safest way is to just use the NickelMenu "switch" to reboot the device each time I finished using FTP (which I intend to use only infrequently).

Per DNSB, as Telnet and FTP effects do not persist after reboot, the device remains secure after reboot even if I need to use WiFi when I am outside, correct?

FYI:

I've cone up with a modified FTP and Telnet definition for NickelMenu that is a true toggle of either one; ie if not running it will enable it; if running it will disable it.
