In
your case, the recovery catalog makes it MUCH MUCH easier! :-) So, I'm
not saying you are incorrect, only that nobody should ever think they are
unrecoverable just because RMAN can not find a backup set record in the
repository or control file
the absolute fall back plan is that you will just have to manually
extract the backup sets from media and recover.

The Rman repository is just another Oracle database. It needs it's own
backup and recovery plan. Worrying about incomplete recovery of this
database in relation to recoverying
Simple export of the rman user usually does the trick.
But then what about the backup of the repository backup.. and so on :)
