I realize this is pedantic, but there's a fundamental 
difference between "cracking" MD5 and looking up pre-computed 
values. Of course, it may be useful to find out what password 
generated some particular md5 hash, but the is only 
non-trivial because the implementation of the hashing 
algorithm did not include salt while hashing.

The only real difference is by using precomputed tables you're front-loading
your work and only doing computations that would normally be needlessly
repetitive once.  Otherwise the "cracking," as it were, is the basically
same.

I don't need to be directly addressed on messages to a mailing list I
obviously subscribe to. ;)
