With Coda the file attributes are always fetched from all available
servers, clients are reponsible for detecting differences between the
replicas. The file contents are fetched from the server that is
estimated to be the fastest (on the assumption that our connection to
that server is the more reliable or that the server is least loaded).
It doesn't matter whether a client reads the whole file or only a little
part, we fetch the whole thing once and keep using the locally cached
copy until the original on the server is changed.
