Results are in. I've now made 2 stoves, one like the design in the link above, and a hybrid. The hybrid pressurizes faster, is cleaner, easier to build, and cooks hotter.
I tested it tonight, and got 2 full cups of water to boil in 6:25 on just under an ounce of alcohol. This is not much slower than my wisperlite, and in all honesty, this thing is HELLA lighter than the wisperlite.
Construction is simple enough, and i'll be making a new windscreen and pot holder in short order to make a complete self storing cook set. the stove nestles in a cat food can that i have a plastic lid for. I use the cat food can as a prewarmer (this accounts for 1/4 ounce of fuel each time you start the stove) to get the stove fuel to boil...this takes about 20 seconds.
Here's the pics:
I tried to get some shots of it burning, but they aren't turning out too well.
