iPhone Daemon Processes and UIApplication's openURL

Question

I have a daemon process which I created running on my iPhone (so yes it is jailbroken). I have been able to use the Audio and CoreLocation frameworks without problems. However when I try to use

NSURL *url = [NSURL URLWithString:@"astraproto://hi"];
[[UIApplication sharedApplication] openURL:url];

it just doesn't open. The protocol is of a custom application. I have tried using the protocol from safari and it works. Is this possible to do from a daemon process which isn't running on the UIApplicationMain and if it isn't is there any other way?

Thanks
