The answer is YES.

Indeed, this is not the case.

More generally, there should not be any `bad' interaction between HiPE & OTP.

Even .beam files containing native code can be happily loaded in a non
hipe-enabled Erlang/OTP system.  The .beam files are `fat' and contain
both native & bytecode.  On the other hand, the native code is in general
not tranferable -- even between systems of the same architecture.
