How to Duplicate Nodes?

I have a simple question which doesn't seem to be answered in the
documentation: How do you make a copy of a node (or better yet, a
node and all of its children)?

I have an application which needs to draw multiple instances of the
same model, but with each instance drawn in a different color.
Unfortunately, I can't seem to use shared or cloned instancing for this,
since color is not an inherited attribute. So I believe I'm stuck
with making a copy of the model for each instance I want to draw, then
setting each leaf node to the desired color. It's ugly, but it might work
if I could figure out how to make copies (short of reading each node's
type and attributes and explicitly re-creating an identical one).

I'd appreciate any clues.
