Yeah, I'm actually trying to expand Spotlight queries into a different format so I can execute them on a SQLite database, and the process doing this is a root-level daemon, which means I can't use NSMetadataQuery, because it returns different results when run as root versus when run as a user.
The lsregister -dump option is intriguing, and as a worst-case scenario, I could execute that via NSTask and parse out the results (though this would definitely be a last resort).
Thanks,
Dave
