Yes. It's important to note that the internals may be changed later,
although that may complicate things if we want to allow people to run
incompatible versions of the daemons. [Another email on that subject is
coming up after this one].
We need to treat the binary on-the-wire ABI for the client<->daemon the
same way as our public ELF library ABI. Never break it, only add to it.
So if we think the internals client<->server needs may change we should
avoid including this code in a release until we're more satisfied with
its longevity.

Dan.
