Hi,
At the Vegas event, I was showing the VSA integrated version of KNM, which utilizes the silent install functions and through an agent procedure installs the gateway software. I don't have access to see where the official link is for the document explaing the installer command line options, but you can download it from my dropbox at dl.dropboxusercontent.com/.../Installer%20command%20line%20options.pdf
Regards,
