So as long as novus doesn't have illegal/copyright material on their gateway and they ban/blacklist anyone that does try do funny business on there then they will be safe yeah? If I wanted to upload something not above board then by creating my own gateway I take responsibility away from them? Is that right? Sounds cool as fuck and something that is uber long term.
My understanding is that currently there's a central website and a central database with the meta data aboutthe files.
Soon
TM - no, I mean soon for real! - there will be a blockchain which carries meta data in transactions and a wallet that can parse the meta data and serve it to a web server.
Once that's implemented, both the files and the information about them are decentralized.
That web server operator might or might not follow DMCA (or other copyright holder) requests depending on the legal situation of the web server and the operator, respectively.
