Hi Peter,

there is a relatively painless way to load several VRML files 
simultaneously: you can e.g. use parallelgraphics's proprietary VRML 
extension "DropSensor" to add aditional shapes via drag and drop (see 
<http://www.parallelgraphics.com/products/sdk/>) -- but you need the 
Cortona player and have to write special WRL files to use the 
DropSensor. FreeWRL or Instant don't like this extension an might even 
crash.
I've been building some VRML files with drag and drop support to explain 
things like gamut mapping or device gamuts in training courses. They are 
really useful to put such things across -- but, as they require 
Parallelgraphics's player, you can only use them when you can assure 
that your audience uses the right player (e.g. in a training classroom). 
AFAIK the current Cortona player doesn't work on Intel Macs with Leopard 
(at least it doesn't work on my MacBook Pro).
Here are two examples. They work with MacOS X 10.4.10 / Safari 2.0.4 / 
Cortona Plug-in 1.0.1d13, but might *crash* or *freeze* other browsers 
or players!:

and

As VRML and X3D support adding and removing objects through Java and 
Javascript, it should be not too complicated to implement similar 
functions for other players, but players like FreeWRL and Instant Player 
are still work in progress.
