OK, so I misunderstood your needs.
sorry, I didn't read the thread completely and just jumped in.

OK. Marhsal-module is nice, but there are disadvantages:
if the marshalled data is loaded but was corrupted, this
can crash your program!
So I would never recommend to use it.
It also possibly could be a security hole, when using that module.
Another reason why I would never recommend it's usage.

Beter write your own implementation of the serialization
on top of OCaml, without of Marhsalling-module (which
is too deep inside the internals of Ocaml, and therefore make things
possibly unreliable!).
