My guess is that you probably don't want exactly the same semantics and
calling conventions in a kernel. But if you're on the same platform, why
not just use the IPCs that you already have there (shared
memory/copyin/copyout, even doors on some platforms).
In a kernel, you *know* the other end is there, and there is no room for
breakage in the middle.
