There is no reason a single library can't have multiple device classes.

If I thought I would ever need to run multiple libraries, I'd be tempted to 
create multiple device classes, one per tape storage pool.

Then if it ever became necessary to move a pool to another library, it would be 
a simple matter to update the device class to point to the new library and move 
the corresponding tapes.

or, use one library for the primary pools and another for the copy pools, or 
define one stgpool in the new library as the next for an existing pool in the 
existing lib.....
