Excellent! Staying with a FAT-16  BTW, have a look at how Puppy Linux
achieves that same goal (in part, using unionfs):

http://www.puppyos.com/flash-puppy.htm
http://www.puppyos.com/development/howpuppyworks.html (section "How Puppy
works, take 1")

Puppy has an X-based GUI, but that's irrelevant to us.

And here is a version for USB keydrives, with dual boot capability: native
(full speed) for BIOSes who know how to boot FAT-16 partitions from "USB
Removable FDD" drives, and QEMU-based (acceptable only on 1.5 GHz Pentium M,
excruciatingly slow on 400 MHz Celeron) to run it inside a VM under Windows:
