The default MIX model is that only channel participants are allowed to subscribe to nodes. A MIX channel MAY allow non-participant subscription to some nodes. This will be handled by clients directly subscribing to the desired PubSub nodes.
The user's server needs to make roster changes as part of the join functionality, as specified in MIX-PAM. This means that the join request to the MIX service will come from the user's server from the user's bare JID.
Peter St Andre provided key early input to MIX and worked on the original specification with Kevin Smith.
