Files on local machines?
Sounds like one massive, security-induced headache to me. If your main building does inextricably blow up during the night, I'm not sure how you could continue working from a different location unless you've included several PC's at a different physical location during the setup of AetherStore. I imagine powercuts would offer several obstacles as well (multiple hardware failure, data loss/corruption etc.)
Although I do understand it's clearly not meant to be used for mission critical data, I'm not convinced it even fills a niche market, especially when the price of centralised storage is so cheap (and the OpenSource tech to replicate the data off site is pretty reasonable as well ;) )
