large VBOs for multiple Drawables

I found some email threads that hinted at this a little, but nothing
seemed very specific.  I have scenes where display lists perform a bit
better than VBOs.  My best guess is because my objects have relatively
small vertex counts (usually between 20 and 200).  Is there any way in
OSG to use one large VBO to store the date for multiple Drawables in
order to minimize buffer state changes?
