This is cool. And the experience of gesture typing is so different from touch-typing on a physical keyboard that I think it might be easier to experiment with or learn new keyboard layouts in this environment.
Way back in the PalmPilot days I used the "Fitaly" keyboard layout (wow, their site is still up and hasn't changed in years: http://www.fitaly.com/fitaly/fitaly.htm) and it was fairly easy to learn (by point of comparison, I've never been able to make the transition from qwerty to dvorak on a real keyboard).

A circular layout might be easy to use with gesture, something like a rotary phone with radius jumps
This loopy gesture-based keyboard won some of the typing speed contests back in the PalmOS days:

I just rediscovered my overlay last week.
These Norvig notebooks are reliably epic.
Wow, I didn't realize that this was part of a series until I saw your comment, Thanks! For everybody else who's interested:

Yes.
Literally every notebook I have read from him I just learn SO much! It's amazing ..

That was an absolutely fascinating read. Great detail and cool solutions.
The minimal work load average problem here seems like it would be a great candidate for simulated annealing. [0] It gets rid of the local maximum problem that the author mentions, without adding a significant amount of additional complexity to the computations.

I was a little disappointed by the lack of attention to detail:
> the A key is half way between the Q and W in the horizontal direction
I'm not sure that's been strictly true of any keyboard I've ever used.

I think you're thinking of hardware keyboards, which are totally irrelevant here - look at the screenshot at the top of the page.
I don't quite get it. Is this much different from after the fact spelling autocorrect in effect?
In regards to the 6th question (one left only partially answered), some of you might find this blog post (posted to HN by my collegue a few months ago) that attempts to answer this question in a lot more detail (and with a lot more computing power) [1].
An aside: we made a python library (specifically intended for use in iPython) to help facilitate answering the exact types of questions posed in this article. A bit more time was spent on performance efficiency and visualization but there were some interesting functions in this notebook that would be a welcomed addition to the library [2].
Although the main point of our work was to determine the least confusing keyboard layout for gesture typing, we designed the library to make it quick and easy to answer all types of questions relating to keyboard input. As an example, at the request of an HN commenter on our previous post, we took a quick look at how the average path length on a random keyboard layout compares to the FITALY keyboard. Shameless plug: the question only took 5-10 minutes to code up and answer using iPython with the library mentioned above ([2]). In case anyone is interested you can find that notebook here [3].
