So, it looks like one can call SMJobCopyDictionary with kSMDomainSystemLaunchd and, in the case of the SMJobBless sample code, com.apple.bsd.SMJobBlessHelper to determine whether or not the helper tool has been installed.
What I am still not sure about is how to check the version number of the tool to see if I need to call SMJobBless again to update the helper tool. I suppose I could encode the version in the label of the tool. So, in the case of the SMJobBless code, one might have: com.apple.bsd.SMJobBlessHelper.3 or something, but I'm guessing there is a better solution then this.
