I don't think we'll see many Walmarts following 708. When this was covered in our IAEI section before it came out in the 2008 NEC, it was applicable to facilities that had been singled out by some government agency (like Civil Defense).
That way the systems in truely critical places like (maybe) 911 Call Centers would be designed to be protected per 780, but not every place would be hit with the expense.
I could foresee a Walmart being a place to house those chased out by a flood, but not a place where major rescue operations would necessarily be headquartered.
BTW, I really don't want to tell the IT guys about the orange smurf tube; I'd rather laugh histerically when they do their own work with a flashlight and standing on a chair...then have to rip it all out because they don't have a CLUE what they're doing.
Remember that old P.T. Barnum quote "Never smarten up a chump".
