The osgcluster example gets and send events between the master and slave instances over UDP packets, the slaves unpack the UDP and pass the events onto the viewer by injecting events the via the EventQueue. So have a look at this example. In OSG-3.3.x and svn/trunk there is also an osgDB::Device base class that allows you to create custom Device objects that can be attached to the View and have it provide the events. Robert.
