Netflix is not supposed to be cacheable by third parties for legal reasons that have absolutely nothing to do with routing. Similar with most streaming services including stupid geolocation usage. If you have sufficient eyeballs, Netflix will work with you to get a local cache set up using their devices. If it is just you and a half dozen neighbors they won't. A far larger problem than the encryption is website design that doesn't cater to low bandwidth links. HTML5 is cool but marking a 10mbyte animation as non-cachable and putting it on the front page of a major bank website is a misuse of resources.

I look forward to your innovations.
The innovation I'd like to see is a multi-level streaming cache. Here's the basic idea: Define a network protocol such as "mlcache" mlcache://data.netflix.com/starwars/chunk12345 is a chunk of some video that netflix has. It's encrypted. The client got the decryption key for that chunk and instructions on how to load the chunks in what order in an authenticated http connection. The client does not connect to data.netflix.com. Instead, it probes an anycast IP address to find the nearest cache. If there is no cache, then it falls back on contacting data.netflix.com directly. If the cache probe returned a unicast IP address for a nearby cache then the client asks the cache to retrieve that chunk instead. If lots of folks using the cache are watching that particular video, the cache can supply the chunk without asking netflix for it again. If the cache doesn't have the chunk, it contacts the next cache upstream. If there is no next cache upstream, it contacts data.netflix.com directly. The cache is not application-specific. Anything willing to talk the cache protocol can use it to fetch chunks of data from any server. In principle this should work for live streams too. The head end server either replies "not yet" or holds the request open until the next chunk of data is available. The cache requests the chunk once and supplies it to all clients once retrieved. Keep the chunks small enough that the caching process delays the live stream by a second or two, no different than the television broadcasts do.
