I don't particularly see this as being helpful, though. To me, it seems like the failure of the experiment would only lead people to the conclusion that Noah's Ark was miraculous.
I think the only way to disprove the Ark is through geological and anthropological evidence, such as Coyote continues to assert. Aside from that, no experiment is really going to have any impact on any Christians' faith or belief system, nor will really change scientists' views on the subject, so I can understand why the ID movement isn't very interested in this sort of thing.
Although, it would make a fun reality TV show: maybe the only one I'd ever watch beyond the first episode.
...most people in general aren't educated enough to understand geological and anthropological evidence that you speak of... But an experiment in a form of a tv reality series. Now, THAT is good evidence that EVERYONE could understand.
I guess you do have a good point: the masses could relate better to reality TV than to science (scary thought, that). Still, the people who can't understand the scientific evidence and who would rely on reality TV for "proof" are still, the way I see it, the people who are likely to shrug at the failure of the experiment and say, "Then it was a miracle." So, I'm not so certain it's important to reach them with this evidence, except in relation to popular votes and court decisions about ID in science classrooms.
Of course, the failure of your Ark experiment would be a fatal blow to Intelligent Design as a scientific endeavour. On the other hand, the success of the experiment would lend some credence to non-religious ID, so it could have interesting implications for the whole genre of creation-style sciences.
