Then in Chapter 14, we illustrate these principles by building an application from the ground up.

As legendary Internet protocol designer Marshall Rose once put it, you can build a good helicopter or you can build a good submarine, but you can’t build something that is both a good helicopter and a good submarine. Trying to use the same tool to solve every problem usually ends in disaster.

This means that XMPP is not a panacea for all Internet usages and, thankfully, the Internet already has time-tested technologies you can use instead for other tasks: HTTP/HTML, BitTorrent, Real-time Transport Protocol, SMTP/POP/IMAP, Usenet, etc.
