I think this is the first time I've heard of NDN, and I've only spent a short while reading about it. My first impression is:
1) It involves addressing chunks of data rather than hosts that hold those chunks. Somewhat like using URLs at the network level. So instead of IP/HTTPS where the network learns of host communications without learning of specific data exchanges, NPN would reveal those specific data exchanges to the network.
2) The mandatory "signature, coupled with data publisher information, enables determination of data provenance..." aspect would cut both ways. For we would be data consumers in some contexts and data producers in other contexts.
I hope I read something to dispel my concern, but I worry about increased metadata exposures and reduced ability to achieve beneficial levels of privacy/anonymity.
