I suggest to add to pubsub nodes journal which will contain all actions
with node since some moment to track changes easily, e.g.:

<journal node="urn:xmpp:microblog:0">
  <update item="2" ts="2010-10-11T00:00:00Z"/>
  <publish item="2" ts="2010-10-10T21:15:17Z"/>
  <retract item="1" ts="2010-10-10T21:14:10Z"/>
</journal>

With ability to retrieve such journal from given moment. Then client
will be able to reproduce all actions since a last online moment simply
to rebuild all node in it's cache to actual state.

Also, I suggest to add revision number to a node which will be
incremented with any action and will be sent with each event to detect
such changes.
