Interesting article about Google fiber and disallowing hosted servers.
It basically says that Google doesn't impose data caps or other restrictions, but this is only achievable if people use it in a "consumer" fashion by not having servers that use large amounts of data continuously (my paraphrase).
While a couple of 3MP CCTV cameras might not be considered servers in the strictest sense, they would fall within the realm of what Google doesn't want on their network.
Some people have made the argument that VSaaS is the next wave of storage, and that the bandwidth availability is quickly catching up. I never see how that math works out, and I think this is another example of why we shouldn't expect cloud storage as a full-on NVR replacement anytime in the next decade.
