Hmmm... 1. Requires new routing protocol/network protocol. (multipath routing) 2. Relies on storage and network capacity with no reliability guaranties. 3. Limited ability to detect bad actors - because of network coding you don't know a) if you have a bad block until you decode it, b) who gave you the bad data until unless you get more redundant copies than you would need to decode the data. Just point 1 alone would require the entire internet backbone to be upgraded. We're still trying to get that done for IPv6, so don't expect to be able to use this in the near future. The other points would make it vulnerable to DoS attacks and even without bad actors it needs large scale and a slowly changing network base to work reliably. But it got published.... So I guess that's worth something?
