I agree with you. But the problem with taking local backups is that
afterwards they have to be sent to the server to which the tape drives are
attached (there is no tape SAN at this customer's site, and no tape drives
will be attached to each DB server.)
So taking local backups means transfering them to the "backup" server,
thus implying some critical code writing to make sure the backup pieces
are correctly transfered; it might also complicate the mechanism that
ensures that these steps are correctly scheduled:
RMAN bkp -> Net transfer -> Bkp to tapes -> Bkp deletion from bkp svr
-> Bkp deletion from DB svr


You are aware of products like Legato Networker?
Would your 'firm' rather loose money by not being able to recover, or
buy Legato Networker?
What your describe sounds heavily like re-engineering Legato
Networker.
Penny wise, pound foolish.

Anyway: as soon as it comes to rman recovery, those savesets *have* to
be located on the *original* location.
I would check my creditcard. Even assuming you are underpaid, you are
not going to get it working robustly. There will always be some black
spot. There are companies specialising in this kind of software, the
fact these companies exist is for a reason. It is called not
re-inventing the wheel.
