Send them your library as is (just copy it to the CD/DVD), and have them add that library to their Calibre with ''Switch/create library...' -> 'Use the previously existing library at the new location'.
They can then copy books between the two libraries (yours and their own) as they wish, metadata and all.
They'll probably have to copy the stuff off the CD and set the files writable; I don't think Calibre can use a read-only library (it needs the metadata.db to be writable, IIRC). Sending them an USB stick might be easier if they aren't very computer-savvy; that will work without any fuss.
