Not possible like this, CSS decryption is only available for image files
since there needs to be a UDF filesystem.
You might be able to either use a fuse driver that does the CSS
decryption on the server side or you make /dev/dvd directly available
via NFS.
The latter solution should be no problem at all in theory (no ioctls are
necessary) but last time I tried things like that someone had added
completely useless code that made using devices files just like normal
files impossible for no good reason at all (that was in sshfs though I
think, not NFS).
