Thanks Nick, 250 talks about two seperate buildings with one service, and 230 talks about one building with two services. I don't think this particular situation has been contempated by the Code. How big a deal would it be to just bond the two ground electrode systems together and go along my merry way?

You should go through the part of 250 about different GEC for separate building, which has some optional installation options, and you could likely use that to justify running the equipment ground back to the house.
