Yes, you'll probably have to build it to CO grade standards, but that isn't exactly rocket surgery, and it seems to me that you peel 3 or 4 layers of crap off the top doing it that way. Unless you're in, say, the Philippines, I can't see the advantage of burying all that stuff underground on a campus-scale deployment. Cheers, -- jra -- Jay R.
