Is it possible to use shared memory with this solution,
I have it working for my daemon now, but have yet to hook
up in the System Preferences plugin,
can shared memory cross sessions?

So they should be the same.
IIRC, a bootstrap daemon is not supposed to answer to notifications
even distributed ones. Security reason I guess.
In Matt's original message, he wrote:
I have two apps running, one is my StartupDaemon and the other is a
System Preference plug-in I made,
When I click on this button I want it to send a notification, that the
Daemon can pick up on,
I'm assuming this means his startup daemon is running as root - in
which case by default distributed notifications won't cross session
boundaries.
The NSDistributedNotificationCenter documentation was updated for
Panther:
http://developer.apple.com/documentation/Cocoa/Reference/Foundation/
ObjC_classic/Classes/NSDistributedNotifctnCtr.html#//apple_ref/doc/
uid/20000396/BBCCIIEI
which points at:
- (void)postNotificationName:(NSString *)name object:(NSString
*)object userInfo:(NSDictionary *)userInfo options:(unsigned)options;
One of the options is NSNotificationPostToAllSessions. This new API
allows the process to decide how wide a distribution its notifications
get.
