Enable Jscript Intellisense for CRM by Leveraging Visual Studio 2008

The promise to have Jscript intellisence over the crm JScript object model has me sold
on the book "CRM as a Rapid Development Platform" (electronic version $49.99) by David Yack.

On David's site you can find a videocast demonstrating the benefit's of intellisence for Crm JScript and how to achieve it. Enable CRM JScript Intellisense

As far as I am aware you need to buy the book to obtain the code that helps you achieve the intellisence in VS 2008.
