For the postbuild script plugin, would be really nice to have the option to select which node (slaves or master) to run the script on. I have a scenario where the slaves do not have access to certain network areas (but the master does) - wanted to use maven to deploy the artifact but slaves can't 'see' anything on port 80 (I'd use the "copy to master" in conjunction with this plugin to perform the maven deploy), so would be awesome to have this functionality.
