Searching shake and rake reveals that it's just loose fill fiberglass. What a pita that will be.
Dinger, when I moved in my 1000 sq ft house fifteen years ago and was much more ambitious, I pushed 38 bags of the cellulose crap through a 2x2 attic access above a closet shelf, crawled up there, broke it up and raked it everywhere with a garden rake. G o o d g r i e f do not do that to yourself. If fiberglass loose fill is 1/2 as dusty as the cellulose any respirator that you use will be instantaneously overwhelmed. I switched to the sandblasting type with the corrugated (like car air filter) type and that thing screamed uncle after about five minutes. Switched to wet rags around my face and finally came out of the attic looking like Jacob Marley from the George C scott Scrooge movie. I can't imagine what it would have felt like if that had been all fiberglass, not cellulose.
The trick with blowing it in, I think, is that you're DONE before you asphyxiate. I'd say wet the stuff down lightly to keep dust down but wetting fiberglass might be a big no-no.
So in summary, I did what you are proposing except with cellulose, not fiberglass. It was terrible. I would not do it a second time without a hazmat suit.
