Works like a charm :)  For those who might benefit, here's the Delphi code
(easily ported to C):

Deserialize:

  xdr := JS_XDRNewMem(fcontext,JSXDR_DECODE);
  if (xdr <> nil) then
  begin
    JS_XDRMemSetData(xdr,data,len);
    Result := (JS_XDRScript(xdr,script) = JS_TRUE);
  end;
  // data is char *, script is JSScript *, len is size_t, and xdr is
JSXDRState *

Serialize:

  xdr := JS_XDRNewMem(fcontext,JSXDR_ENCODE);
  if (xdr <> nil) and (JS_XDRScript(xdr,fscript) = JS_TRUE) then
    data := JS_XDRMemGetData(xdr,@len);
  // here data is just void *

Many thanks Brendan :)
