I believe that you're correct, but that (unless I'm missing something)
libudisks and the daemon communicate using the Dbus message API. So it
should be possible to use the library with a FreeBSD-specific daemon (that
already exists) providing the same messaging interface.

I'm mostly interested in a library that will let me know whether/when
removable storage devices (like USB memory sticks) or media (like CDs or
DVDs) become available for mounting. Am I looking in the wrong place with
libudisks?
