How about the TreeLob? Did you finished it? It has recursive manner for 
child things as would this structure lob do.

Layout objects have a manner to have everything ready before rendering.
Therefore we could not easily use vob scene to pick up the structure 
points. But, only the inner lob knows where the structure points are.
Otoh, it's ok to know the exact structure for layout objects but not 
actually the way it looks on screen.

Let's assume we can do the previous tray like structure lob. How to make 
it fast enought to change between scenes? We could use couple of them and 
interpolate between them. I think this is trivial(I'm assuming that it's 
trivial or it's impossible) if we don't show spatial views' buoys that are 
started from ring 1+n buoys.

I don't see a reason for it. But I see more potential possibilities 
to use layout objects when can do it gloriously :)
