Hi there!
I wrote an app for the Windows Phone 7 Marketplace called "Warhammer Dice Master" that is available now either through the Marketplace app on any Windows Phone 7 device or at the Zune Market website.
It's a simple app but it allows players and GMs to use the "WFRP Lite" approach if they don't have the custom dice.
I'm also working on a web-based version so those without a Windows Phone can use the app as well.
Cheers!
