An AFS-aware drop-in replacement for the "cp" command would make sense, it
seems - it would detect if both the source and destination paths are in
AFS land and issue the proper server directives to do the copy
server-to-server or within the same server, but otherwise function as a
normal "cp" command. Hm, I wonder if you might even be able to have it
create an OldFiles-style replica of the file? Or is that only on a
per-volume level?
