> though it also has some advantages—it's nice to be able to message someone not online Just because you don't require servers, doesn't mean that you can't have servers optionally as a relay. Your client tell would tell the clients of your contacts to send messages to a server specified by you when they can't reach you directly. For instance the server could be run by the company behind the messaging app you're using and could send you push notifications. You could still switch the server at will without loosing your identity.
