Simon U., in another off-list exchange, reminded me that Rinternals.h has

  void R_Serialize(SEXP s, R_outpstream_t stream);
  SEXP R_Unserialize(R_inpstream_t stream);


  R_Init*PStream, R_InitFile*PStream, R_InitConn*PStream

That might be worth a shot if you want to serialize at the C++ level.
