The Ultimate Abo course by Cody Lundin is the closest thing I know of deprivation type course. I believe the BOSS school pushes you to, but not as long...
Hope you like rat on the barbie...

No cell phones, no pagers, no GPS. Find out what its like to become truly self-sufficient in the wilderness! The Ultimate Abo allows you to step back in time a thousand years and experience nature on Her own terms. Youll spend the first six days of your journey at a remote, wilderness base camp.
From this landscape, you will gather and fashion all of your gear from natural materials. For the last three days, your tribe will leave the base camp, setting out on foot to explore, travel, and live like nomadic hunter-gatherers using only the primitive gear we have created. This is not just another outdoor course, its a new outlook on life allowing you to live what youve learned!
Experience nine full days of life-sustaining wisdom including all the fun of the Essential Abo and Provident Primitive courses plus: constructing willow pack-frames, stone and bone tools, the art of primitive cooking including stone boiling, hot rock ovens, wooden grills, coal cooking and more, primitive fishing techniques, cattail and bulrush sleeping mats, finger weaving pack straps and belts, making and using pine-pitch glue, traveling with primitive gear, safe and effective camp site selection, natural crafting, safe knife use techniques, and much more! Two meals a day are included for the first six days; well hunt and gather food as a tribe for the last three.
Note: The Ultimate Abo continues to be an ALSS icon course and is based upon Codys 30-day Aboriginal Living Skills class he developed and taught for Prescott College for nearly a decade. He has a special permit from the state of Arizona allowing you unparalleled realistic hunting and gathering experiences.
