Fair enough...but I'd still think that having a single input makes
more sense for all users (but admittedly this is a usability issue).

Are you suggesting a javascript that automatically sets the focus to
the next segment when a certain character count has been reached? If so,
I thought I'd seen fairly conclusive evidence that this sort of thing
should be avoided, as it can and will cause confusion - going against
expected browser behaviour, often not triggering any indication to
assistive technology that the focus has indeed moved and, when implemented
badly, can prevent users from tabbing back ... or are we just talking about
limiting the number of characters that can be entered (in which case
a simple maxlength attribute on the input would suffice)?
