This isn't really true, though. When you support PEP you are automatically subscribed *only to those nodes that you advertise in your caps to which you wish to be subscribed* for the contacts in your roster. So if you advertise "I want timezone autosubs" in your caps, you'll be subscribed to only the timezone PEP nodes of your contacts. This doesn't seem like more data on the network than with polling - at least to me it seems like vastly fewer. /K
