Passphrases v Password

[Cathy Hubbs <hubbs () AMERICAN EDU>]

Greetings,
American University is moving to require passphrases, 16 character 
minimum, with upper and lower case requirement for standard users (staff, 
students, and faculty).

I would love to hear from anyone that has gone down this path and 
experiences from their customers.

Thanks

Cathy
