Many odd things are going on with Google's gTalk server at gmail.com. One odd thing is that I get presence stanzas pushed to me by the server with my own full JID as the from attribute, at regular (?) times.

Another issue is that I am not allowed to send normal messages to myself, at least if I specify my bare JID as the to attribute according to the XMPP standards. However, if I set my full JID as the address, it gets delivered OK.

Now and then there have been a lot of discussions about the JID Escaping XEP and I have contributed myself since I found it problematic that a user may enter a JID where its parts cannot be uniquely identified, and therefore is invalid from a users perspective.

While implementing stream compression I noted it says that "Negotiation of stream compression SHOULD be completed before authentication via SASL". This is also the way ejabberd 1.1.2 and OpenFire 3.3.2 works.

Sander brought my attention to a project by Armando Jagucki to produce a PEP server component for OpenFire and his recent advances. Since there is a test server at jabber.esoteriq.net I wasn't late to test it.
