Pointer to proposed PubSub code?

From reading some earlier threads, a community member has proposed some pubsub code for inclusion in Smack. I wondered if someone could post a pointer to this code?

I’‘ve created a very, very limited PubSub library for a research project and I know of the su-smack SMACK extension as well. I hoped to look at these implementations, the proposed smack add-on and learn from them. I’‘m working with the latest SMACK 3.0 beta, so I’'m hoping to use the new features/support as much as possible…

Any help would be greatly appreciated. Cheers!
