Yeah, same here. Hmm... /me ponders. How about publishers publish any 
packet (with some possible restrictions) to a topic, then that message 
gets duplicated and sent out to all subscribers to that topic? The 
pubsub component would check to make sure the packet is from the correct 
publisher. This way practically any type of packet could be easily 
published to subscribers. What functionality would be lost if this was 
done over having all publishings in the iq packet under the 
jabber:iq:pubsub namespace? Whatever functionality is lost, I'm sure it 
could be re-created in the any-packet-for-publishing method I describe.
