i don't have much experience with it but have any of y'all looked into the
rate option that 'throttles RMAN so that a backup job does not consume
excessive bandwidth on the computer'

if your database is always active this might be something to look into.  10g
has more options where you can specify windows of resource usage and
resource priorities.
