Another thing that whoever is implementing BLOBS will have to be aware of
is making sure that access to individual BLOBS is controlled by the
'owning' table.

I don't know if an implementation has been settled on, but at one point it
was suggested that BLOBs be stored in a single table. I suspect this
approach would not work for the above reason.

Also, is there any reason why BLOBs need to be stored in a table at all?
Can lower level I/O routines to be used to chain groups of pages together?

Finally, is there a plan for the BLOB implementation that is available for
comment?
