"Helper" applications

Subject: "Helper" applications

My preference pane contains in the Resources folder a "helper" application. I've got a communication between them going with distributed objects. The preference pane needs to be able to open and close the helper (similar to the Growl and MySQL preference panes), and see if it is currently running. I can use [[NSWorkspace sharedWorkspace] launchedApplications] and see if any of those match the file path of the helper app's bundle. I can launch the helper app with [[NSWorkspace sharedWorkspace] openFile:]. I can monitor whether or not it's open with notifications... Where I'm stuck is how to close it. There doesn't seem to be a (recommended) way to access its NSApplication instance to terminate it. How can I close the helper app? _______________________________________________
