Think about this:

How often in the last year have you used a tape volume from your copy
pool, other than to possibly run one or two RESTORE VOLUME commands on
bad primary pool tapes? Is your need to be that granular really
practical?

If you're still nervous about non-collocated copy pools, how about
running a MOVE NODEDATA on the copy pool copies of files on your 3-5
most critical servers?

Also keep in mind that group collocation will (hopefully) be in TSM 5.3,
which is scheduled to GA in December.
