I love this idea, but I'm not sure it's really feasible for most people. When you don't have a lot of land, having a giant mountain of compost is probably not the greatest idea. Not to mention the logistics of finding and retrieving good quality compost material seems like it might be a little difficult. But, I'm not someone who has the patience to maintain nice compost piles, either, so my opinion is probably skewed. I would love to see some examples of someone using this method on a much smaller scale.
