If they crack it, they might be able to automatically change the password to
a readable one.

I was under the understand that passwords of over 14 characters were stored
with a more secure hash, therefore 14 characters passwords were harder to
crack, due to the more secure hash. Windows will create two different hashes
for passwords shorting than 14 characters, I do believe.

Just use a non-printable character in your password and cracking is
useless...if they crack it, they can't read what they cracked. ;)

Perhaps they should enable more/all password components to
handle much
longer passwords/phrases.

A passphrase consisting of 7 words and 12 bits of entropy per a word 
is as guessable as a password with 14 characters and 6 bits of entropy 
per a character. You get 84 bits of total entropy in both cases.

The only advantage of passphrases is that lusers might find long 
random sequences of words easier to remember than long random 
sequences of characters.

(But wait: 12 bits of entropy per a word--this is equivalent to a 
uniform choice of one word out of 4096. 4 thousand? That might exceed 
an average luser's vocabulary by an order of magnitude! ;>)
