One other reason to use NSData is to hide certain information from casual
users... though in my testing it is smaller as well which is a nice side
effect.
Just trying to be sure that if I use archivedDataWithRootObject on 10.5 and
write it to disk, then read it with 10.4's unarchivedDataWithRootObject,
that all will be ok.
