Upgrading VMware Tools Without a Reboot Using PowerCLI

Historically, one of my biggest little annoyances with a VMware version upgrade has been upgrading VMware tools. In vSphere 5.5, VMware added the ability to update tools without a reboot. If you were manually kicking off the tools upgrade all you need to do is enter the following features into the advanced settings box /s /v"/qn REBOOT=ReallySuppress? This is great and causes the tool update to only lose one ping instead of requiring a full restart.
