Instead of the VIN, how about the emblem/turn signal on the side? That should be enough to tell if it was a founder's, signature or production model and wouldn't require the photographer to hover over the windshield.
The Facebook post Jeddi linked says "I saw a few more Model X's at the factory today. Couple of them were Founder editions and few more were getting through the final inspection stages (I would assume)."
I interpret that to mean that at least one was not a Founders edition though, which seems unlikely, given the lack of news on Bonnie's thread. The post also does show a closeup of one of the turn signal emblems with the "founder" script.
