While v0.6.0 is in final baking mode, I've started work on v0.7.0 which introduces the ability to send messages to only one endpoint node in a private chat mode.
This is not the same as DMing another radio, because I can't physically do that, but it does mean you can send to a single recipient node instead of everyone who subscribes to you.
It'll get more refined as I work on it, but I have already started and have mapped out how it *should* work.
