I was just wondering if anyone knew of a one-disk (floppy or cd-rom)
linux distro for web browsing.

I realize it's an odd request.  

I'm going to take a computer security course that involves my bringing
a sacrificial laptop.  I sure don't want much information on that
box.  But it would be cool if I could boot it from some fixed media
and just use it to read email through a browser, so I'm not totally
out of touch.

Bringing two laptops doesn't seem very appealing!!!!
