hm... i'm unable to post comments to this tracker, so i post it here now:

do we try to make the api of osg fresco-like or do we just write a 
CORBA-wrapper?
for the how-to-access-the-nodes-question... may to the same like in 
Micros~1 Win... have something like *handles* or proxy-objects that can 
associated with a node.
maybe have a general interface on this proxys for manipulating state...
but in first, we should try to define what scene-graph we want. are we 
just try to wrap osg with CORBA?
or do we want to make osg frescoish first? ;) or are they already the same?
