Update:
BOT arrived the other day. Here are a few pics.
It fits nicely on top of my Emberlit. The gasket on the lid was unaffected by cooking:
Here's my intended kit - BOT, Emberlit, Kifaru Sm. Pullout w/essentials, SOL Emergency Bivy, Camelback Bottle Pouch. It all fits in the Camelback, except for the stove:
Contents of the Kifaru Pullout - 10' of p-cord, roll of duct tape, signal mirror, whistle, compass, matches/lighter/fire stick, several types of tinder, quick energy food, H20-proof marker, and water treatment:
Also, as hoped, my Toaks 750ml Ti cup nests perfectly inside, and I can still get the whole Pullout in:
This all came together just as I had hoped. The whole kit pictured above, including the Toaks mug and a folding Ti spork is shy of 2.5lbs. Obviously, these last two items aren't critical and there are a few other things I could streamline or drop to make it even lighter. But this kit provides decent shelter, ways to make a fire and cook, a little quick sustenance, a couple signaling devices, and a way to treat water in the event that I don't fire up the stove to boil.
As I mentioned before, this kit is intended to live in a day pack, so other essential items I would generally have with me to accompany this any time I go out are essential clothing (and a backup layer), a knife (or two), a small 1st Aid Kit and a firearm. Depending on the situation, I also have a silnylon tarp that is easy to throw in the pack and weighs nothing.
More to come...
