  Sounds different to me. For pipe, you need to launch the qemu program
in a given way, you can't attach to it later (and /proc/$pid/fd/* trick
is really limited to Linux).
  W.r.t. PTY access I assume only one program can locally attach to
it, my patch may allow:
   - remote access if using port based access
   - multiple simultaneous external access

So I tend to think the goals and use are differents, it's not about
redirecting console, but rather allow remote asynchonous control over
qemu instance(s).
