Multiple picks should query and retrieve the target each time. This
is how you retrieve changes or updates to a linked node.
If coupled with an engine, this is even a simple networked animation feature
(e.g. the amazing fish cam http://mosaic.mcom.com/fishcam/fishcam.html).
For the sake of graphics & network efficiency, browsers might insist
on a little latency between repeated identical mouse picks.

In effect un-embed edits the scene graph. Options might be U)ndo or
B)ack. An overachieving viewer might even make a vrml editor
available. It is probably better not to be too restrictive on the first
go round.
