Right now you can assign only image bump map. This is a bump map based on
black&white images (see UV Mapping 'Bark' tab). That bump map will be 
common
for roots, branches and twigs. Using image map for texture and image 
bump map
you can achieve very realistic result. But that functionality works only 
for mesh
export.

Usually you shouldn't use triangles/mesh for manual modelling. POV-Tree can
export mesh files which are very useful when you have to duplicate the same
tree many times (e.g. forest). In case of mesh POV-Ray needs memory only
for one tree that's why you won't get 'out of memory' message even for 
hundreds
trees.

All mesh tree elements are not closed objects. They (roots, branches and 
twigs)
have hollows. Leaves are flat objects. So, I don't think 'hollow' 
keyword will make
any difference. Or maybe I didn't understand your point.
