One additional point to the proprietary nature of the database. It is my understanding that a large consideration for the design of the database, is down to TSM's random access storage pools and the ability of the database technology to employ 'bit vectors' to track the location of allocated and free blocks in the random access storage pools.
With the growing popularity of sequential disk volumes, it *might* be the case that random access storage pools could be 'phased out' and thus negating the need for bit vectors in the database architecture. At this point, a move to DB2 for the back end db technology could be a real possibility. Please feel free to correct my understanding if it is way off the mark.

I also heard that IBM has (had ?) plans to move to DB2 with V6 (this is speculation, of course).
