Ok, I have another question: We have: Contact A with one resource (resource is 'res1'): [EMAIL PROTECTED]/res1 And Contact B with two resources: [EMAIL PROTECTED]/res1 priority 20 [EMAIL PROTECTED]/res2 priority 10 They are not subscribed to each other and do NOT share any presence information. Contact A sends a bare JID message to contact B. Contact B receives the message at res1 (due to highest priority), and answers from that resource. Contact A receives the full JID of that resource now and 'binds' the conversation to it and they chat. Later Contact B switches to his laptop, with another client bound to the other resource 'res2'. And he sends a message to the bare JID (because the client there doesn't know the full JID of contact A) of contact A. How should contact A proceed? Should he bind (and reply) the conversation to res2? Should he make a second 'chat session', which is probably not very intuitive for the user because he just wanted to talk to contact B and when he got two options to send the message, what should he do (he doesn't even know which resource is the 'right' one, or whether 'res1' maybe went offline)? What if they share presence, should contact A's client determine from the highest priority resource where the message should go to?
