I don't have any specific machine information as to what does and
doesn't support it.

Check online specs/user guides/feature lists from your manufacturer.
Ask your sales rep. Consult the almighty oracle that resides at
google.com. And any other method you'd normally use to find out
information on specific motherboards and other hardware components.

I'm not sure I'd be a fan of it. On one hand, you could just have one
usb pen drive that you use to boot all the nodes. Nice in theory, but I
really don't want to have to touch a slave node just to reboot it.
Other than that, you'd have a nice usb key sticking out of either the
front or rear of all your machines like a sore thumb, and would be quite
easy to accidently brush against and break/pull-out/snap-off in your usb
I have heard of people using usb devices (ipod's) to boot public kiosk
machines so that if a machine were cracked into, the real system files
couldn't be tampered with, and a reboot would wipe any added back doors.
But that's a very different situation.
