No... It's not a matter of flipping a switch on their existing equipment and all of a sudden they have a ton of extra bandwidth to give to customers. In order to provide lots of people higher cable modem speeds you need to spend money on head-end equipment, fiber plant, and then cable plant to segment your network enough to keep it from being over-subscribed. If they already had D3 capable equipment and just 'flipped the switch' any one person might have a whole lot of bandwidth at 4AM, but it will start to slow to a crawl when everyone else is using it.

Cable ISPs don't have a lot of unused bandwidth they're sitting on to just be a-holes to everyone.

The drones were stationed at an Air Force base, but were owned (and presumably operated) by the Customs and Border Enforcement folks. I believe the ones being used to hunt for Dorner are also Customs.

I beg to differ. While most cable ISPs have a fiber network with tons of bandwidth, that last mile over coax will always have comparatively terrible bandwidth, especially upstream. They can split the network up by lowering the number of houses on each coax downstream, but that comes at an added cost of headend equipment and the like. It's a careful balance of cost/performance. The CDN would probably help a lot with upstream costs/bandwidth but it won't do diddly for congestion in the last mile.
I don't have Comcast, so I don't know what CTV is, but if it's just cable TV, that's just broadcast traffic that doesn't take up much room. If it's VOD, it's probably compressed terribly and there's an associated cost increase for the service that helps offset the bandwidth used.

I'm down as well Hepcat... Hell, I'll even buy the first couple of pitchers ; P
