Maybe we can work around this, perhaps by adding a user-selectable flag in exodusII_io_helper which can switch the Hex27 node ordering when the user knows the exodus files will be read with vtk/paraview? For reading in those same files back to Libmesh, I'm not sure. We could have it try one ordering, check the Jacobian sign and if negative, try the other ordering?
