So it could in fact be "DayTrip Proof"? I'm pretty decent using a light....
Why couldn't the MSR ring be used in the exact same way as a line loc, i.e. on the tent as you describe with a loop on the ground stake or dead man? It just looks like a fat line loc to me unless I am missing something about the design. I've always found line locs annoying to use and prefer the hitch method that releases itself (no clue on the name. It's the knot Andrew Skurka often recommends). It's quick and easy with bare hands but more annoying with cold hands and/or gloves and I'm finding it harder to tie now that I wear reading glasses, which I never seem to have handy when I'm pitching a tarp or tent.
The generic version of the MSR cam rings was like $5.87 for a 10 pack on Amazon so I got a package so I can mess around in the yard with these, line locs that I already have on the tent, etc
