XenServer Build from USB Stick

I saw this interesting post in the citrix blogs , a guide to installing XenServer via a bootable USB stick. I plan to use this method to update my XenServer from v4 to v5 very soon as my Little shuttle XPC has no CD drive. I will post back if i have any problems with the method detailed in this link
