[GSBN] Any experience with Rice Hulls?

Hello,

Has anybody used Rice Hulls as insulation as proposed by Paul Olivier?

It looks like it could be an easier method of wrapping than it would be 
with SB. It might also be a cheap and easy to use material to add 
insulation to an existing roof (when it can be poured in from above). I 
have yet to try it... so I would appreciate learning from your 
experiences before experimenting with it on my home.
