Does anyone know of an internet kiosk version of knoppix that is able to be used on a business network (not allowed to browse the network) and only be able to access one or two sites? I am trying to find one for a friend that needs it for his customers. It will allow them to browse his internet page and see his products that aren't in the show room.

If so...
Which one
How do I secure it from being an open door to the local lan
How do I keep it from accessing the rest of the (windows) computers
Make an install on the HDD so it will respond faster

Thanks.
