Much of the mesh handling code assumes the mesh is on R2. In some situations only minor changes to the code would be needed to support S2 meshes. In other situations (e.g. code that relies on projecting polygons to equal area meshes and then use rgeos/sp for boolean operations) more substantial updates will be required.
