Why does it have to be automatic?  Something like xlockmore or slock can
be tied to a keyboard shortcut, such as <Ctrl>+<Alt>+<L>.  If for some
reason you require automatic locking, though, you could perhaps set up
some kind of Bluetooth connection detection if you have a Bluetooth
enabled cellphone in your pocket (or something else that would work as a
Bluetooth token) and if your computer has the right hardware.  I imagine
writing a daemon in Perl or Ruby that checks for loss of a Bluetooth
connection would be easier than getting Bluetooth working in the first
place might be, depending on the state of Bluetooth support in FreeBSD.

I'm not really well-versed in the ephemera of what is used to determine
"inactivity" on a computer, but if it's reasonably easy (or if there's a
Perl module for it), that seems like the obvious way to handle it --
though of course that may present problems, such as false positives on
detecting "inactivity" when watching a movie on the computer or something
like that.

I used to be a NeXTie, and the there had a really nifty little feature. I'm surprised it's not been copied into other screensaver
applications since, as it's pretty simple.  They just had a facility where
moving the mouse cursor to one corner of the screen and leaving it still
for a few seconds would cause the screen saver / screen lock to come on
straight away.

Conversely you could designate another corner of the screen as "don't turn
on screensaver even after an extended period of idleness".  Being a NeXT app
this was all configurable by dragging little '+' or '-' icons around a
scaled down image of the screen, or off it entirely if you didn't want that
