The temp seems to be the bigger issue. Keeping it cool enough to prevent spoilage.
Normally, I'd say bury the thing, but we're not supposed to be disturbing the playa surface that much. But how about evaporative cooling? Depending on the type of vessel you are using, I love my German sauerkraut crock with the water seal, you could wrap the whole thing tightly in several layers of towels. At night it will insulate it and keep it warmer. In the day time, you could pour water on the towels to provide cooling to the vessel.
Dust- yes! How to plan to incorporate the inevitable playa dust in the kraut...
And evaporative cooling is a great idea! I've not tried it before (besides myself and soaking my hat and shirt in ice water to keep cool) but it seems like it could work with careful monitoring.
I've only used glass mason jars for fermenting.
