No, rsync does not support transferring data between two daemons in a
single run.  You can have Host-A run a script to pull the data from
Host-B and then push it to Host-C.  If that is undesirable and you are
not limited to accessing the source and destination via the daemons,
then you may be able to have one of Host-B, Host-C act as a client and
connect to the other, either directly or with the help of Host-A.  I
will have more specific suggestions if you provide some more information
about your scenario.
