I think you're right; I was thinking about that point too because DB2
doesn't have index-organised tables (well, sort of: MDC).
I was confused because IBM seem to have a patent on (1), even though it
seems exactly like the original NCR/Teradata implementation, which
predates the patent filing by many years. Wierd.
It's a minefield of patents....

True, not all copies work :-)
