I think adapters are the key.  Adapt objects to IFileAccessMode,
IOwnership, IGroupOwnership, IObjectSize, and IFileTimes.  (Those names
might not be right, but they are a start.)  Perhaps there might even be an
"IUnix_ls" view that looks up those adapters, supplying a default when
there is no adapter found.

One thing to keep in mind is that although most FTP clients ask for
extended listings, they don't actually do anything with most of the
information besides show it to the user.  The size is probably the only
field (besides the name) that influences the behavior of the client.
