Hi Charlie,
Even though the prognosis for an exterior application may be bleak due to the size and climate there is another possibility for you to get the benefits of papercrete. If you are redoing the interior of this structure, papercrete can be sprayed. If you remove the interior wall covering and open the wall cavity, you could spray it full of PC and it would increase insulation, strength, and sound deadening. Papercrete has generally shown to have 3 to 3.5 R value per inch and a compressive strength of around 300 pounds per square inch. If the siding won't work you could still use PC to strengthen the walls, create a solid impervious layer and re-apply the interior wall. You would have to come up with an alternative for the exterior.
If you aren't going to redo the interior then this suggestion is moot.

Thanks Charmaine and Spaceman,
Based on your comments and more research around the Web I've decided to not attempt the papercrete siding idea. I knew there was a reason all the examples seem to be from the arid Southwest. Ah well,
Thanks for your time,
Charlie
