Our current scenario is that we are archiving from machine A to machine
B.  Our hot spare is machine C, thus we are pulling the files via
network from machine B to machine C, hence the reason I don't believe
db_standby will work as it has no facility (rsync,scp) to retrieve the
files from another machine.
