short version: wow.
slightly longer version: friggin’ awesome in every respect.
detailed version: as previously mentioned there was some confusion/oddness with the LoginHook I planned to use for iTunes Library sync’ing. But that has since been worked out. NOTE: sudo vi /etc/ttys won’t do it but sudo defaults write com.apple.loginwindow LoginHook /your/script/path/here will. Remember to check the perms on your directories, kids.
