In fact a change like that wouldn't be too difficult as the prototypes
for octave's binary format

extern bool
save_binary_data (std::ostream& os, const octave_value& tc,
                  const std::string& name, const std::string& doc,
                  bool mark_as_global, bool save_as_floats);

extern std::string
read_binary_data (std::istream& is, bool swap,
                  oct_mach_info::float_format fmt,
                  const std::string& filename, bool& global,
                  octave_value& tc, std::string& doc);

would tell you. You just need a wrapper to setup the iostreams on both
sides and then install the variables into memory on the reader's side...
Should be relatively easy..
