Linux in your browser

Literally.

(486 emulator written in javascript that boots up to a linux shell prompt – yes, I said javascript)

Nifty. So, uh, can one actually use it for anything?

How does the Internet not implode upon it self when someone uses this?

Ha, very cute. Now write a web browser that supports JavaScript within that Linux environment that runs in JavaScript within a web browser…

The internet will implode once someone compiles Apache in there and hosts a website.

All he needs is basic vga support, and you could build X and run Firefox :)
