I don't really grasp what you're trying to do, but 2 things come
to mind:
1) view.rename("value", "newvalue") might help
2) tmp = vw[:] will turn a ROViewer into a (in memory) View, so you
could add a column.
I wouldn't worry too much about processing time - what you're
doing is already pretty intensive.
