Not for my customer. Internal accounting means that the storage team gets paid 
for each allocated GB on a monthly basis. They have 
stacks of IO bandwidth and CPU cycles to spare outside of their daily busy 
period. I can't think of a better spend of their time 
than a scheduled dedup.

I don't think you can make this generalisation. For most people, yes, but not 
everyone.
