I'm not sure how scotch-guard works, and I think 'chemical' is a bit of 
a nebulous term. I always thought nanotech refers to discrete artifacts 
smaller than a micron (i.e., whose size is best measured in nanometres). 
Wikipedia have quite a good run-down.

I don't know anything about that. I think I heard of a demonstration 
some time ago, but what would you use it for?
