I just read the posts in this thread, and promptly forgot who posted what, and when, but I did retain some bits and thought I'd just generally answer.

I hope it's still relevent.
Firstly, I basically use this method up by the house, but our actual garden is done in beds, 4' X 20', which are planted biointensively, on centers, using companion planting, and open pollinate-heirloom varieties.
Someone mentioned corn and beans. Absolutely. Put the beans in and let them climb up the corn, and put some small pumpkins in, for good measure.
For years I wouldn't grow corn. Too greedy of a feeder, too space consuming etc. Then, 2 years ago I came across, Painted Mountain.
It gets to be 4-5' tall, but still has 7" ears, and does not drain the soil like other types. It tolerates poor soil, is cold and drought tolerant, and is early. It looks like Indian corn, which makes it rich in anti-oxidants, and it's uses include: Fresh eating, flour, hominy.
The first year I tried it, it went in late, then my water failed to a section of the garden, the corn section, so the corn got nearly no water. I pretty much wrote it off, but gave it a bit of water now and then.
By the 4th of July, we had 2' corn! We had nice ears off 3' plants that year, and I took them back for seed.
So, just a thought, for those who want to play with just a small block of corn, just because. Or maybe just set it off in a corner where you don't have planting areas. It's pretty darned hardy, and doesn't take much work.
