What can we do with the problem? Since from the distributed nature of the network, I think that the only thing we can do is to assign the problem of tracking changes to the receiver's server: it can catch events and store current revision of the node and then client can be notified that some new events were received and that it should retrieve new items manually. > > Peter > -- With best regards, Sergey Dobrov, XMPP Developer and JRuDevels.org founder.
