Reclamation has been repeatedly studied, and, in general, the  
conclusion matches the following excerpt from a Cisco Journal article:

If you can come up with credible figures indicating that there are at  
least 28 /8s worth of reclaimable space out there, then, reclamation  
efforts might be more interesting, but, I tend to doubt that is the  
case. If you can't reclaim at least 14 /8s, you don't even buy an  
additional year.
