At first the task seems simple. The client observer class implements a
RemoteObserver interface and exports a stub which it passes to the "server".

However,
this assumes that;
 1. The notifier code in Observable catches Exceptions, and doesn't get
freaked out over intermittent network problems.
 2. The Observer can "loose" events during network problems.
 3. The Observer is able to detect that its stub has been garbage collected,
possibly due to network problems.


And such subject is larger than I have energy to discuss here. There is a
specification around Remote Events, being part of Jini which may contain
discussions around this topic.
