Insect Rearing In Permaculture

Just thought I would put it out there (a flavour of 'crazy' for us westerners). After seeing this article today in the guardian (http://www.theguardian.com/sustainable-business/eating-insects-yuck-factor-un-report), I was wondering if anybody has raised insects for food within a permaculture system.

Maybe there are additional by-products and other uses (pest control) that edible insects could provide? Chicken tractor, pig tractor, roach tractor,...

Here is a report linked from within the article (I have not read through it fully yet, mind you):

Some other links I scrouged from an internet search:

cheers.

I've raised insects, but not for food (at least not for people). I've raised silkworms for silk and fed the pupae to chickens. I've also raised polyphemus moths for silk and released the adult moths when they emerged. Both are labor intensive and probably not worth doing just for food (though people do eat silkworm pupae) but I'm going to do it again for fiber.
