It's probably worth noting that such media:

a) will not work with anything that is based on disk images;
b) will not be bootable on most existing systems.

Both of these are going to be issues for people in real-life use (and
yes, people boot from USB disks -- trust me, when it doesn't work they
send the bug reports to *me* rather than to the hw/bios vendors.) Of
course, so is XP compatibility.
