Deploying an Image from a USB Drive

Deploying an Image from a USB Drive

Hi, we are trying to use OS Deployer to image some new laptops that don't have any onboard ethernet. We want to try and avoid using a USB to ethernet dongle or trying to deploy over the WiFi connection. Our thought was to install PE components on an external USB drive along with the deployment image, then boot off the USB drive and run installation from there. Is this type of deployment possible?
