Has anyone ever done an interactive kiosk before?

A developer and me (i'm a designer) are about to develop an interactive kiosk and have a few questions we can't find the answers to.

It will be web hosted like a site.

Do you need to use specific touch screen software?

What size do you design and build to, is it the screen resolution of 1280 x 1024?

Hope someone can help

Cheers

Darren
