After some long hard thought, i've decided against building dry-composting toilets out here in Saudi for the reason that fine organic matter--such as sawdust or shredded newspaper--is not widely available in our rural area, nor is any organic matter aside from other manure, for that matter.
This has led me to search for other equally efficient systems, but there's a nagging element that I can't get out of my head: dung beetles.
One of my workers made a fresh deposit up on the mountain back in the Spring, and I happened to come upon it 15 minutes later--there were a good 20-30 dung beetles swarming the thing, and it was completely cleaned up after another 30 minutes.
Worms, at least the kind generally used for vermicomposting have a very hard time in this climate naturally--termites are generally the ones that fill that niche here in the desert.
Is there a way i could substitute dung beetles for worms in a system like Australia's A&A to deal with blackwater/humanure? I'm fishing for ideas here more than anything else.

Wow, 30 minutes? I wish we had dung beetles like that here in California... wouldn't even have to bury poo while backpacking! Maybe you should capture some and test how long it takes them to clean up poo (and for the smell to go away) in an enclosed space (albeit with windows). That would give you an idea how many anti-odor measures you would need to take.
