How about eSATA? Surely an eSATA enclosure for 10 drives won't be more 
expensive than ten individual usb enclosures?!

AD does not have acls. NTFS does. The closet things to NTFS acls in UNIX 
is nfs4 acls. That you can get with ZFS. I suggest that you give 
OpenSolaris a shot instead. Or you can be one of the testers for 
ntfs-3g's acl implementation...

Have you ever used winbind? It maps AD credentials to POSIX credentials.
