Mary & Jacob;

Tensioned mesh, providing precompression to the bales makes
pins redundant.

It sounds very much like you don't intend to embed the external pins within
the plaster skins. (ie if the pins on the exterior were embedded, additional furring
would be required to create the ventilation airspace behind the clapboards.)

Not having the pins embedded is like placing rebar outside of the concrete which
it is supposed to be reinforcing.

Furthermore, unless the pins were something like 2x2s (which tend to go 
snakey unless well restrained at intervals not exceeding 24" or so ...twine
through the bales isn't going to do it )  there is going to be a lot of lumber 
consumed just for not much more than just nailers, probably enough  
lumber to  construct a structural double stud wall.

It sounds like you have planned on constructing a structural frame of some
sort (since the bales are serving only as infill) so the frame + "pins" could
amount to about 3x the amount of lumber that is consumed in a 
conventional stick frame. 

Of course, my not having seen a drawing of the proposed wall section,
I could be full of hooey... or maybe beans ?

re: Source for straw

I'd go talk to a dairy farmer or someone who keeps horses
in your neighbourhood. These folks are hard core straw junkies.
I'm sure that they would know who has straw bales available.
