What you'll really want to avoid is binding and unbinding VBOs as much as
possible.  For objects with multiple materials, my object class uses
separate VBOs.  For objects with around 10 materials, that's quite a few
operations.  I'm going to have to convert the VBOs to an interleaved VBO to
raise performance.  Long story short, I reiterate: try to minimize VBO
binding.
