Here's what I ended up doing for the DSS computer boot lacing.
The loop on top of the boot holds tight once there is a bit of tension on the wrist loop.
I also just rigged this set-up on my wrist slate:
The way the cord lock is "tethered" to the slate allows me to tighten the bungee with just one hand by just pulling on the short bungee loop. Better than my older set-up without the tether, where I needed to hands to set the tension.

Interesting method. Are they easy to take off, as well, if you need to loosen it? Seems like it could get pretty tight with that loop locking it down.
I like your idea with the slate, though. Very clever.
