I've been checking out OpenFire recently and am now trying to ascertain whether I can make a pubsub node with multiple collection nodes as parents. It would be very handy for the architecture I have in mind. Unfortunately, while the XEPs make it very clear this should be possible for an appropriate hierarchy of nodes, I can't tell which hierach(y/ies) are implemented by OpenFire, and whether they support this feature at all. I've asked on the official forums but haven't gotten any replies - I heard there were a number of people experienced with OpenFire here so I'm hoping you guys can shed light on this for me. Thanks in advance!
