User Tune or User Mood set via PEP are seen only on same server and other Openfire servers. I tested it on my local server and some public Openfire servers.
XML console indicates that client doesn’t receive pubsub event on other servers. (My client is Psi 0.12-RC1)
On the other hand we have ejabberd2 server where PEP is correctly(?) sent to Openfire, other ejabberd, jabberd and even Google Talk.
