If your users chose remotely good passwords, this could take a long long 
time.  At least on the order of days.  I tried cracking passwords on my 
system (md5 encrtyped) with John the Ripper and it basically has to use 
a brute-force + dictionary attack because md5 is not a reversible function.

I would say this isn't the way to migrate passwords.  The best thing to 
do is to use the same encryption on both systems so the /etc/passwd file 
is still valid.
