Yes.

In the local case I do some post processing - so the isLocal() check 
ensures that the post processing is done once.

In both cases I'm generating application events out of the observation 
events, like a page has changed event, removed etc. The post processing 
is actually done based on this application events, so if a page has 
changed, some action is started. Therefore my application events need to 
be marked as local as well.

So basically my code looks like this:
      if (event.isLocal() ) {
          // send local app event
      } else {
          // send remote app event
      }
