Request: Apple Keyboard with Trackpad for MacBook "Addicts"

We use MacBook Pros and before I bought the 27" iMac i7 for home use, my main machine at home was also a MacBook Pro. I find the MacBook keyboards with the integrated trackpad a lot more ergonomic than the separate Apple Keyboard.

So, how about creating an Apple Keyboard that replicates the MacBook experience, integrating a wrist rest and trackpad to the keyboard? Third party products like this exist, but I doubt the trackpads have multitouch support (two finger scrolling is especially important).
