John was a tool which was good a decade ago
The tools have moved on - just because not everyone here has used precomputed tables and quadratic methods does not mean that an attacker does not know of them. I am sure that Barclays Capital has enough of a presence to attract the corporate criminal type...
I reiterate - the real issue is to stop an attacker getting this info in the first place.
Secure Server plus secure client settings in group policy on a MSFT network and this is no longer an issue. "An Ounce of Prevention is worth a pound of cure"...

Try the password of your choice with alt 255 in the middle currently things like lopht and john don't get near it

HI
1st it does not make them untouchable
Next, MOST applications do not accept Alt+xxx based passwords - very few users will use them as well
Do your users authenticate via a Radius systems, the web...? Any of these will not accept Alt+xxx chars.
Most users will have issues using this
the following does not make a very memerable password - see how often it is remembered?
¦ß?|?O11s

Why aren't alt characters feasible alt255 is an easy one for anyone to remember and if the policy for passwords dictates the requirement then most large firms would accept this especially if it made the password in the current view untouchable for the for seable future
