     I *think* motion has a setting where you can set a minimum time 
delay between frame triggers, doesn't it?  I'm not too worried about a 
few extra frames here and there.  It's just that, if I go for a 
fixed-interval intervalometer, I'm going to have to hand-edit out 
12hrs/day of "off shift" footage.
     If there's a good way to post-process out too-similar frames during 
the "stitching" process, I could go that route.  It just seemed simpler 
to not grab them in the first place.

     Hmmm... that strikes me as a good way to get a very ugly time-lapse 
video in the end, though.  This will probably be pulling snaps for 
*weeks,* and eventually compiled into a long-term time-lapse video.
