Standard practices say no non-root process gets to talk to the Internet on a port less than 1024. How, then, could I get Node talking on port 80 on EC2?

Alter the port the script talks to from 8000 to 80:
}).listen(80);

If you had other ideas or suggestions please leave a comment.
The first time I bought a Pi I was enormously frustrated with myself because I didn't own all of this stuff. Kept having to order things off of Amazon and wait to get started... very irritating. This is all good stuff to have laying around anyway:
