I agree a big picture discussion is welcome.

In my branch:

  https://github.com/glondu/unison/tree/umarshal

I use a simple custom serialization format on which the protocol is
built. The core is in src/ubase/umarshal.ml. The changes may look big,
but are pretty simple and systematic. The constraints for this version
were: 1) do not depend on OCaml version and 2) do not add dependencies.
I also previously did two other trials (protobuf and bin-prot), but only
with constraint 1.

Note that my branch is not that, but I think is an interesting first
step towards it (which would need even more invasive changes).
