Adding support for disabling checksums is almost trivial as it only requires flipping a value in the control file. And I have somewhere sitting around a similarly simple tool for turning on checksums while the database is offline. FWIW, based on customers and fellow conference goers I have talked to most would gladly take the performance hit, but not the downtime to turn it on on an existing database.
