The network as a featureless data stream is another example of the same
``traditional'' thinking in the UNIX community.  Actually, the
datagram-based schemes favoured in the US (oversimplifying grossly, we
Europeans have a preference for connection-based systems which do deliver
streams) can provide nice record boundaries, which could in turn be used to
delimit labels for the proposed tape archive format (after adding some
reliability and sequencing).  Just because the format is based on IS 1003
for labelled magnetic tapes does not mean to say that it cannot be used on
other media, networks among tham.  After all, tar's a format for blocked
magnetic tapes, but that hasn't stopped us moving tar archives over
networks.
