I've done the farm half-step. One thing one immediately notices is
it gets cold.
after awhile since there is no 'inside' that gets kind of old.
if months pass and a branch falls on your tent in a rainstorm inverting it, you might actually trade even a woman for a hot shower, a rusty cot, and some college credits

I think what would be the most realistic and involve less commitment, would be to try to get a bunch of people involved in the same WOOF program (probably in Europe) and then go on week/2 or so long excursions and document everything. from there hell..you might be able to get some kind of funding.
another thing I imagine would be important would be having some kind of meditation practice, or just having a really strong sense of self, as mentioned there is not all that much to do at times to occupy the mind the way modern civilization 'conveniently' does for us.
