which is awesome however, there are a couple of missing details. one, there is a large gap between the seat tube and the rear wheel, which could be used to hold something.
the other is if there are any random thoughts on where to put a kickstand? i was considering it butcher bike style to prop the front wheel, but am interested in any helpful suggestions.
oh, and this is my 1st post to point83, so I'm sure it will be fruitful.

This is point83. The area behind the seat should hold both a wine bottle and a flask. In a more serious suggestion, three water bottle bosses ala Salsa could hold their huge cages which are good for tool bags or wine bottles.
We need to figure out how to build a power take off from your open BB shell, and what useful things to do with the power.

finally an updated photo for the anti-abortion crowds. what a beast!
seriously though, that big gap is where you instal the 1L propane bottle & flame-shooting bits.

Interesting choice on the twin down-stays. is the idea to be strong in tension but let the BB flex a bit? oh, and what did you use for a steertube?
Behind the seat tube: a fifth of whiskey would surely be a popular choice. water bottle bosses are versatile, though, can put them to lots of uses.
Whatever the stand is, needs to be in front and needs to be double-sided for stability when loading. My first thought was a triangular stand that swivels around the font axle, is that what you mean by butcher bike style? Something coming off the rack would be my second thought.
maybe the bottom bracket can generate some kind of heat source?

I think traditional PTO uses are best: Winch, mower, baler, snowblower, manure spreader, etc. Though a PTO-driven music box could be nice.
As for behind the seat, I'd try to figure out a nice hard-sided(lockable) box to go there. Maybe coroplast prototype (I've got lots), then build something nice out of wood or metal. The bike also seems to be asking for a nicely integrated dedicated U-lock holder.
You could also build a sandbox like locomotives have, for winter traction.

The U-lock holder is going to be made by putting two bridges the right distance apart on the twin downtubes. The U-lock will hang in between.
The bike got twin downtubes for multiple reasons:
1) Rory's theme with this bike is super light. We did the math and the twin small diameter downtubes weighed less than the 1 3/8" x 0.058 material that we had for a single downtube.
2) The donor bike was lugged and the way that the downtube was hacked off didn't leave us a lot of area to braze a new one on. This is what the downtube hole looks like:
Other ways in which the Turdhauler is super light: we externally butted the cargo tube to 8/5/8. Not in the normal bike sense, but 0.080/0.050/0.080. Man, that was annoying. The head tube is also externally butted. Ignore the overweight metal everywhere else, the 47cm chainstays, and the fact that the frame probably weighs 10lbs.
The steerer tube was made by press fitting in a piece of 0.995x~0.060" tubing (tapered) into the base of 1 1/8" x 0.065. I asked some smart builders how to do it, and that is what they recommended.

the bike also has some key lightweight component decisions, too. for instance, but not having either a front brake or a front derailer, I'm sure the bike saves at least 780 grams. not too mention the tri align 3 v-brakes, which also doubles as a obnoxious noise making device.

i think in honor of all the work alex did on your bike, a bottom-bracket driven lathe and rear triangle mounted torch setup seems appropriate. that way your cargobike can self-replicate.

6 beers look like they could fit in a line between those two top tubes with the right container, wouldn't hinder leg movement at all.
