Windows 7: Winpe for W7 (WAIK)

Hi all
Anybody managed to create a Windows PE disk for Windows 7

I've downloaded the WAIK for Windows 7 RC (build 7100) and am creating a WinPE recovery disk with Acronis on it. - There's instructions on the Acronis site on how to create and add the plugin.

Anybody got any documentation on how to add other drivers / apps to it.

I'd like to have a nice decent recovery Windows 7 disk.

I know I'll have to build another one after the RC expires since I'll need a new WAIK but if I can create a winpe disk once creating a new one should just be really easy.


Cheers
