NetShift uses a standard browser (either Netscape Navigator
or Microsoft Internet Explorer) as the "engine" behind a public
kiosk interface, letting you provide Internet and Web access
but protecting the operating system and computer. It supports
touch screens and/or a mouse with an attractive, easy-to-use
interface. A keyboard isn't even needed since one is supplied
onscreen and can be used by touch or mouse. Some of
Netshift's features include email, blocking certain network
protocols, banner advertising, and branding. NetShift is a good
solution if you need to provide public Internet access and yet
maintain the security of the kiosk setup.
