It worked just fine, and if I'd wanted to spend more than 30 minutes, a combination of tweaking sudoers and writing a few shellscripts could have given instant mounting of thumb drives (and probably DVDs). I understand that FreeBSD has kqueue and kevent, which apparently do some of the same things. According to http://en.wikipedia.org/wiki/Kqueue , it's available in all the major BSDs. So your idea sounds doable, always assuming you can make a high level interface that calls either inotify or kqueue.
