I might be one of the first here to implement this in a dag cluster at a 
customer site today, I can report that it is easy to setup and it runs fine 
with the 6.4 TSM BA client.

This feature "Back up DAG databases to a common node." is nice and works fine 
with the testing I have done so far.
This feature "Coordinate backups between DAG members so only one copy is backed 
up per backup cycle." is true but "coordinate" is a funny choice of words.
:-)
