Much more, however, can be done to enhance CloudMoV to
have product-level performance. In the current prototype, we do
not enable sharing of encoded streams (in the same format/bit
rate) among surrogates of different users. In our future work,
such sharing can be enabled and carried out in a peer-to-peer
fashion, e.g., the surrogate of a newly joined user may fetch the
transcoded streams directly from other surrogates, if they are
encoded in the format/bit rate that the new user wants.
