@cjd And how would that work? Would each server have its own articles, and with every lookup offer you list of servers that are shared and have that particular article (no matter the content)?
@cjd For instance, I would be reading gamergate(a)freespeechextremist.com and there, I would click trump, and got offered Trump from every federated instance?
I'm thinking remote edits should be possible, but only based on a level of trust between instances. Maybe each article has an owner or group of owners and they can delegate edit rights to others, local or remote...
