To this end, ''when:takenOffline'' was implemented in order for developers to be able to install observers on an far reference which are notified when the object pointed to is taken offline.

As an example, the instant messenger application can clean certain resources when a buddy shuts down its instant messenger application as follows:+On the client side, taking offline an object results in a permanent disconnection of the remote references pointing to it.
