Thomas, Thanks. I re-wrote my blender scripts to accommodate both version, since it seems like other visualization programs generally output bonds as two cylinders. What I would love, though I'm not even sure its possible with vrml2, would be export some 'additional' info (like chain, resnum) that each object was associated with.
