Kiosk Question - Lock User In

As usual, your very thorough analysis and report are super input.

Our current requirement will need to let people fill in
their name and address and possibly even CC# number.

I'm not sure that blocking the keyboard is going to work.
Well, try we could put a point and click keyboard on screen,
but that will raise user resistance to our goal: get their
name and address and hopefully a donation.
Would people actually fill in their entire address on a screen
keyboard? that will be the question.

The "public" traffic we are talking about is in the vicinity of 20-150 
a day, where we would be very luck to get 30% of that traffic to
actually "sign the guest book"

So I guess this probably qualifies as "very light use"

On the other hand, our place here is slowly becoming "famous"
and traffic is going up every, the future will be different....
