Although most commonly used for HTTP networking, node.js works great for any situation involving lots of waiting... like, say, other forms of networking!
We'll take this time to discuss using node.js for networking over different protocols, including anything that's not accessed using a web browser (yes, WebDAV is fair game, even though it's HTTP).
Some subjects we brainstormed at our last meeting:

• Torrents
• UDP
• Multicast (Frank)
• XMPP (XTENSIBLE MESSAGING AND PRESENCE PROTOCOL)
• Serial
• MLLP
• SSH (Frank)
• SMTP (Dusty)
• FTP
• SFTP
• SIP
• Wireshark with node!!! Luke
• Airplay
• UPNP

If you have a project using one of these (or other) protocols, we'd love to see it and hear your opinions on working on it!
Also, we'll be exploring the Travis CI API as the next API in the "an API a month" series.
