Hey guys, someone emailed me a link to this message board where a fellow by the name of Dietmar managed to hack XP into booting from any USB device by mod'ing the USB driver registry entries. I haven't had the time to test this myself, but if it indeed works it's a huge leap (IMO) for XP hacking. Others in the XPe community had tried hacking the boot order and CriticalDevicesDatabase registry entries before, but were never successful. This guy did it. There are still a few questions I have on how well it'll work with, for instance, ACPI (same problem there currently exists in XP and XPe when booting from a removable CF disk where ACPI freezes the PC).
I'm going to be out of town for a few days so I won't be able to try it out until late next week. BTW, this is different than what BartPE does, which is USB RAM booting. This actually boots and runs the OS from the USB disk. Note that you could also use it with a USB external HDD which then removes the need for EWF.
