You can't decrypt them, but you can make brute force attacks by running a 
dictionary against the encrypted passwords, get a hold of something like 
cracker jack 1.4 and a big dictionary.  Also, run the passwd on the system 
whose file you grabbed so that you know if a word has to have a number at 
some point, or must contain a capitla letter, then pre-process your 
dictionary so that it meets those requirements.  Of course, i am not 
advocating that you do this, just that if you were, theoretically trying 
to get passwords, this would be a way to do it.
