My god, this is awful.
(a) encryption will not help you if it is standardised. If it is not standardised,
then all it will do is delay understanding. If it can be decrypted by the vm,
it can be decrypted by the analyst.
(b) Time to market penalties are so incredibly brutal now, I question
whether obfuscating byte-code is at all necessary, simply because most people
don't have time to analyse source code, let alone byte code.
(c) Ocaml applications are so rare (compared to C/++), you can consider not only
Ocaml byte code, but the Ocaml source code an excellent obfuscater.
(d) Commercial programs rarely implement unpublished, hard to discover ideas.
Patents are so easy to acquire you are far better off using patent protection.
(e) Those who are willing to rip you off by reverse engineering are probably
willing to do it by sheer piracy. e.g 2nd and 3rd world markets.

The problem is there is a lot of value exchange that isn't represented by
the face of the bill. Ocaml itself is a case in point.
