The exception i see is thrown in ProcessHostController.cs, line 148:

  if (!runningEvent.WaitOne (15000, false)) {
    references--;
    throw new ApplicationException ("Couldn't create a remote process");
  }

I'm typing this from a different machine, so i can't copy & paste the
stacktrace. The behavior i'm seeing is that it waits 15seconds and
then throws the exception. I don't know enough about Remoting/the
codebase to fully understand what it's doing/waiting for during those
15 seconds.

Makes sense.

Nothing. It's just that D-Bus seems to become the defacto standard for
IPC in GNOME. Mono has built-in support via Remoting though.

IIRC Beagle uses D-Bus for communicating with different processes? (i
could very well be wrong).
