When I was a young teenager in the 90s, the thing that blew my mind when I got my first computer was that it turned out that _all computers were servers_. The computer didn't need to be in a rack form factor, or expensive, or any of that. It just needed Winsock, TCP/IP, and that was it! My computer was the same as any other computer on the Internet.

So, while this post is cool, I wish there was less emphasis on the hardware, which is pretty irrelevant for running a Node-base app and serving it to the Internet. You also don't need a static IP—you just need to figure out dynamic DNS :).
