After a correction to the ocamlbuild tags file the above works
correctly. So now I have:

open Camlp4.PreCast
open Syntax
let eval_string s = Camlp4.Struct.Token.Eval.string ~strict:() s


let string_of_experiment_data data =
   let data = sexp_of_experiment_data data in
   let s = Sexplib.Sexp.to_string_hum data in
   eval_string s


which does the job. Don't know if the hex-encoding strategy
is better though.
