I don't want to complain about this much - it seems like a cool little project. But from the linked page and the Wiki, it seems to have been created in near-ignorance of the Artificial Life efforts of the early-mid 1990s. That's a shame, because a lot of people did a lot of interesting things with this idea back then, and it might be worth being aware of hwo that turned out before diving into the idea again.
Thomas Ray's "Tierra" would be as good of a starting point as any, or either of the two Artificial Life volumes published by Addison Wesley in that era.
