[Xquartz-dev] LSBackgroundOnly at runtime

So, I don't have much experience with launch-services, open-step, or cocoa... so I'm going to be needing some crutches for a while... I think I figured out what I need to do to eliminate the second dock icon. I need to manage the foreground/background-ness of the application such that the launcher behaves as if LSBackgroundOnly=true and the server behaves as if LSBackgroundOnly=false. How does one go about changing this at runtime to push a background app into the foreground or visa-versa? It looks like NSApplication.hide() isn't right... that just causes the windows to hide, not push the app into the background... any help? Thanks, Jeremy
