The version of XBMC That I am playing with (XBMClive 9.11) has the capability you seem to feel is needed. In fact I was so impressed with it that I redid my librarian to its style and capabilities. XBMC does its lookups based on what it finds as folders in the Movie, TV, and Music shares. It then looks them up in selected on line reference data base(s) and supplies all of what you seem to want. My only issue was with the TV Episode lookups, but since I am just tinkering around wit it I did not delve into how to correct it.

XBMC acts in some sense as a library manager. I really prefer DVD Profiler for that solution. One of these days I will build a workflow manager to manage the entry of the disk into DVD profiler and its ripping to the NAS. I am sure some interested soul could integrate the output of DVD Profiler into XBMC so that it uses the DVD Profiler exported XML file as the data base in which to look up the disk info.

I do agree though it is not, as it stands, a CI solution.
