Hello Matthew Thanks for the input.
The closest I can think of would be [XEP-0283], which is currently deferred. It results in a a slew of presence unsubscribes from the old JID and subscribes to the new JID, which sounds like what you want. I know there is an implementation at a specific service provider and its official clients, but not sure of anyone else implementing it. This was very close to what I was looking for. The main difference with what I wanted to do was that the redirection request is sent in a presence stanza. I would want a request/response mechanism, so that the client sending the request can take appropriate action (like sending a chat message before unsubscribing client2) if the destination client does not understand or declines the request. (The XEP also assumed that the old JID would vanish and that all contacts would be moved. I see cases where only individual contacts are moved. But that's only a conceptual difference I believe.) I contacted Tory Patnoe to see if there was any interest to awaken XEP-0283 again and/or make some changes to it, but at this time he was not interested. But he gave me permission to propose a new proposal with similar ideas. Would this be a good idea or do you already now see a problem with this approach? Best regards, Peter Waher
