In fact, I just found out today that the vendor already does something with
Oracle replication. We may or may not go with that because my ideal
situation is still having the whole system mirrored-- OS and all-- and I
don't think even Oracle RAC Server does that.

These guys have some pretty heavy refs, and are partnered with IBM (which is
how I found out about them), so they're at least not totally bogus.
Apparently, the program simply takes advantage of Oracle replication but adds
a layer to it by keeping the rest of the computer sync'd and monitoring the
Oracle instances. If an instance goes down, the server it's on comes
off-line cleanly and the backup is initiated.
I've seen it live (with DB2 anyway) and it's pretty impressive.
