Davedarko was way ahead of me. He has a perfect little board that breaks out the pins for an add-on module. 

The modules I have been eyeballing have the pins swapped, so I stole his work and modified it including removing the nice calendar silkscreen and adding a header for swapping data and clock. I also move vcc to the end because more of those are available on the adafruit modules I have coming. I sent off an urgent order to OSHpark since I am in PDX and I think they can pull this off in time.

I have no idea if there will be room for the headers on front or on back. May need to solder blob it.

beats deadbug by a smidge I think...
