There is no real hazard since linux boots ro by default and then tries to 
remount rw. knoppix etc use this as you know. So there is no problem to 
boot from a write protected disk-on-key and run with root in ramdisk. 
Speed is ram speed (booting is reasonably fast unless you use something 
really huge, like kde). You can also use two keys one ro with the system 
and one rw for data.

I have never actually seen a firewire storeage device boot a board but I 
heard it can be done.
