CommandBlock Redstone Output

Hey guys,

I'm having quite a bit of trouble trying to set the (redstone) output of a commandblock (to a comparator).
I know the output of a commandblock seems to be buggy on bukkit servers anyway (always generates an output, even if the command fails), but that's not the point.
I want to be able to control the output, so that I can set it to on and off whenever I like.

I've tried the following code, sadly without success:

Code:

 
public void setPowered(CommandBlock state, boolean power) {
        Command c = (Command) state.getData();
        c.setPowered(power);
        state.setData(c);
        state.update(true, true);
    }

I am able to turn the commandblock "off" by just setting it to stone and then back to a commandblock. Thats not a nice solution, but it works. However, i have not discovered any way to power a commandblock which produces no output yet.
I have also tried to execute a command and then catching it with onCommand and returning true/false, however, this has no impact at all.
Maybe it is possible to turn it on by just making the commandblock execute a (dummy) command?
That would be all I need, i guess.

Does anyone know a nice way to achieve this?

Thanks,
