There is such a very nice device on the market like Dacal CD Library [url]http://www.dacal.com.tw/dc300.htm[/url] .
Although their own soft is rather poor.
But some software builders have added support for this device in their soft already (for example, "All My Movies" [url]http://www.bolidesoft.com/allmymovies.html[/url]). So I can draw a conclusion it's possible in OCD as well.
I think it'll be very useful and it'll beat down many of your competitors ;)
