What I had in mind is, while as you well said, you can link the data in a pub in any way you need, the distribution model is fixed. The only way to change that is creating more pubs.
I think the distribution model is an integral part of the data structure in a general p2p setting and needs to be customizable, within reason.
Cheers!
I think I understand a bit of your concern, although note that the pubs aren't necessarily required for replication in SSB, one can use onion routing, physical devices (sneaker nets), local area connections, etc. But I agree, that there are more areas to improve, such as changing the network/capabilities keys on the fly from within a message to ratchet the distribution, making reference to content hashes within different network keys, etc. I'm curious if your work takes any of this into account? Thanks again.
