[x3d-public] [x3dom-users] port this example to X3DOM?

Yes, the script that uses directOut is like a DOM script.
Operationally, I think it is important to recognize that the directOut 
in x3d was designed to not produce an event directly. The x3d event is 
produced when the target node field is changed. In other worls, see 
that you cannot route an event from the directOut. The changed event 
must be generated by watching the target field of the node used by the 
directOut.
