I probaby meant to say 'pad of single use passwords', but made some 
mistakes in both the terminology in use and my writing.  ;)

Yes, a big limitation is distributing the passwords.
Single use passwords are usually transmitted out of band.  I nthe case of 
banks, they send a new list of 50 or a 100 or so passwords on a 
plasticized piece of paper via mail.  It folds up the size of a credit 
card, but much, much thinner.  A new one gets sent automatically when you 
get near the end of the old one.

If you have your own system, then a lot can be put on a single A4.

Single use passwords still require a secur emethod of transmitting the
password. So I'd guess they have limited applicability.
