the hay bale thing sounds appealing, but you have to have a separate structural frame, and give up a lot of floor space to the thick walls. framing and sealing around windows would be an area of concern too. i hope it works out for you, r leo.
for me, i have to be able to get normal contractor types to build things so that my clients can have a predictable price and outcome. experimenting with new methods of construction would be a good way for me to get my a$$ sued out of business if there were problems.
so non professionals have to be the vangard of experimentation. like in many fields.

Nice thing about SB construction is the walls, insulation and sheathing are all done when the bales are stacked.
There are load bearing SB structures where no frame is needed. Threaded rods are used to compress the bales to the foundation then the walls are topped with a wood or poured concrete bond beam.
Good friend of mine build his SB house and installed siding and sheetrock. You would never know its a SB. He and his wife did all the work. Their utility bills are a fraction of other homes the same size.
There's a number of ways to build a house thats "green", more energy efficient and durable than conventional stick framing. Its just not as quick to go up and may not be code accepted.
Cob, strawbale... even old tires filled with dirt to name a few.
Hope you have a big compessor for the tirolessa.
