I think it could be done, but it would require use of a secondary control
file to avoid locking issues if you tried to do it all in processing (or
just a plain old shell script of some sort to handle it externally).

Basically, I thought you could change the map file, and then just run
autoshuf to rewrite the key/data segments (and use dxmaint to rebuild
indices).

Make sense, anyone?

I won't get into the unstructured data aspect of it from a design point of
view.  But -technically- I thought it was possible.
