Locking Browser for Kiosk-style interface

Howdy all,

Has anyone come across an app that allows for locking the user (via a password or other technique) inside a web browser for kiosk-like behavior? My company would like to be able to allow users to use iPod Touches to access web pages on a local network, but not to allow the users to exit the browser and use other apps.

Does something like this exist?

Thanks!

Nothing so far exists...that sucks.

For a minute I thought that you meant about blocking certain applications on the iPhone, which is physically possible by drilling down the settings menus to General>Restrictions
