I noticed steve added the nice feature to sleep the display via a hot corner, but is there a way for us devs to hook into it? I am currently using a pmset hack which i would prefer to use a cleaner method

Undocumented, use at your own risk, etc. It ends up involving more IOKit than Cocoa, as it turns out.

#include <CoreFoundation/CoreFoundation.h>
#include <IOKit/IOKitLib.h>

int dimDisplayNow(void) { io_registry_entry_t r = IORegistryEntryFromPath(kIOMasterPortDefault, "IOService:/IOResources/ IODisplayWrangler"); if(!r) return 1; int err = IORegistryEntrySetCFProperty(r, CFSTR("IORequestIdle"), kCFBooleanTrue); IOObjectRelease(r); return err; }
