Kicker.bundle may or may not be what you're looking for. I've done an "ugly" hack to have scripts run whenever I change network locations... it has its flaws, but it works for me. It's probably not the right way to do these things...

Some of the info on that site may not be completely accurate, but I have referenced other pages which may be helpful.

How can I detect when the network location has been changed? I figure it is something to do with the System Configuration framework, but I can't find much documentation on it.

What I want to do is write a program to be able detect network location changes and then run a script when this occurs.

This is the direction I'm going now (which doesn't work):

#import <Foundation/Foundation.h>
#import <SystemConfiguration/SystemConfiguration.h>

void sc_callback(SCPreferencesRef prefs,
                 SCPreferencesNotification notificationType,
                 void *info)
{
    NSLog(@"callback called!");
}

int main (int argc, const char * argv[])
{
    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
    SCPreferencesRef scpref = NULL;
    SCPreferencesContext prefcontext;
    CFRunLoopRef rlref = NULL;

    bzero(&prefcontext,sizeof(SCPreferencesContext));

scpref = SCPreferencesCreate(NULL,CFSTR("TEST"),CFSTR("Setup:/ Network/Global/IPv4"));
SCPreferencesSetCallback(scpref,sc_callback,&prefcontext);


    rlref = [[NSRunLoop currentRunLoop] getCFRunLoop];

SCPreferencesScheduleWithRunLoop (scpref,rlref,kCFRunLoopDefaultMode);
[[NSRunLoop currentRunLoop] run];


    if (scpref != NULL)
    {
        CFRelease(scpref);
        scpref = NULL;
    }

    [pool release];
    return 0;
}
