David, Since you updated the schematics, etc could you run the BOM to generate a parts list and stick it in the wiki folder - just want to double check that I have sufficient quantity of parts on hand when the boards arrive. I would do it but the tools don't run well on Mac yet and I have not installed them in any of my VMs yet.
