Haha! Why not? Back to the Unix philosophy that everything is a file. :)

I can see some practical use for this in terms of resource manipulation. The page gets into being able to download videos (YouTube right now it seems) or live editing a page. You could use an extension for that (like Greasemonkey) but this probably lets you use your normal tools (awk, cat, etc.)

For downloading, youtube-dl is probably better right now, but who knows where this will go. It's kind of a fun idea if nothing else.
