Thanks for this! I think I'm still digesting, but I do find the contrast you're drawing between OT and CRDTs interesting. I don't think I had ever seen the fundamental difference between them to be the network topology, but I can't quite claim to understand either in sufficient depth.
Btw, Wave-style OT needs a central server, but there are other forms of OT that do not. They mention this in your link. If your OT system can satisfy the TP2 propery you can do n-n synchronization but still have what you'd call an OT system.
