After a nice long wait in Australia Post, the Rev.02 boards have finally arrived (on the right):

I should have these made up in the next day or so.

Client board assembly:

While it seems odd to have two USB ports on the client, the USB port at the bottom is used for firmware programming of the Ranging module. While it might not be used often, the cost to have different board manufacturing setups outweighs the cost of the extra part, so I've left it in.

Edit: It lives!
