A new reality show?

After reading a conversation about communism today, I got an idea for a reality show. I am sure I mentioned the idea before, but now I think I'd refine it a bit.

There should be a lot of participants, at least 10 thousand, maybe 20. Judging from the number of people whom I hear say that communism was a badly implemented but basically sound idea, that number of people should be really easy to find.

Each participant is provided with rations for a few days, and some tools. They can grow their own food (the show should be filmed somewhere where stuff actually grows), forage for it, or produce goods and/or services and sell them to the outside world and buy food from there.

The participants can organize in any kind of groups and make their own rules. They can leave the area and the show freely, unless prevented from doing so by other participants.

I wonder what kind of communism they'd build in the end.
