I was thinking about this a little while ago and I figured you could big holes, say 6" into the styrofoam and place the stuff into the center of the wall.  You would use the holes to tie the cob on either side together and give it more strength.

I doubt the wall will be as strong as a solid cob wall, but I think you'd get a lot better R value and you could always add more cob to both side to compensate.
