Ah, that's a slightly different definition of verifiable than I had in mind. I was thinking of schemes to allow voters to not only verify that they voted, but that their vote counted towards their intended candidate. I suppose it depends on what precisely is to be verified. The scheme you describe allows for verification that a ballot has been received/sent/counted, depending on details, which may or may not be verifiable enough depending on who you ask.
