This form widget allows you to just display data in a rendered form, not giving the user the opportunity to change it. The initial data will just be carried through the form and showed to the user.
In combination with snipped 1184 you can make this even tamper safe. ;-)

I may be missing something, but how does the form pass back the value for the field? Even in conjunction with 1184.
