It should work for most normal users. :-)

Sure -- but it's not a complete solution. You have to pick an "n" and
then when you get n+1 devices (or a device that doesn't get unmounted
properly), you have to add another entry into the fstab. But, adding 2
or 3 would probably work for most situations.
Also, as you imply with your alternative fstabs, some of the USB
keydrives may be partitioned (I don't remember if they are or not).
Floppy drives (which use the usb-storage drive) are not, so they use
/dev/sda. Zip discs usually have the 4th partition set, and the others
blank, so they use /dev/sda4. I seem to remember USB keydrives using
/dev/sda, but they might also use /dev/sda1.
MacOS X does this Right. Kudzu could too, but to my knowledge, but it
doesn't seem to have been added to any of the versions I've used.

Same here -- I primarily used RHEL derivitaves and Fedora, occasionally
use Debian, and play with Gentoo from time-to-time.
