xbmc does the job aggregating different sources into a library just fine - but you also have the option of doing the same on your NAS using unionfs, with the added bonus that other machines on your network just see one source.
I use ZFS on freenas now, but for many years quite happily had my own 'fake raid' setup (there's no raid and no redundancy though!)
I had multiple, independent disks that I used to ftp movies to, filling one up and then moving on to the next one.
I combined all the disks using unionfs and (because they were all movies for my network) set up a read only samba share:
mount -t unionfs -o ro -o noatime /mnt/SATA-I/Movies/ /mnt/Movies/
mount -t unionfs -o ro -o noatime /mnt/SATA-II/Movies/ /mnt/Movies/
mount -t unionfs -o ro -o noatime /mnt/SATA-III/Movies/ /mnt/Movies/
Worked great for my usage - Full bandwidth to the disk while reading/writing, and shows as a single volume share to the network. Redundancy wasn't hugely important to me obviously, losing a single disk loses you a single disk's worth of content (non-media 'important' files were simply rsync'd between disks.
