A bit late, but QWebSockets is now an official part of Qt 5.3.
QtWebSockets will be proposed for inclusion into the official Qt distribution as an add-on.Please raise your votes on the mailing list email@example.com.

I have just started a proposal for a new StackExchange site. The site is about Open Source Licensing, a topic on which a lot of programmers and companies have questions about.
You can find the proposal at: http://area51.stackexchange.com/proposals/58715/open-source-licensing.
QWebSockets is a pure Qt implementation of the HTML5 WebSocket specification. It supports both text and binary messages, frame- and message-based processing and can be used to implement clients and servers. The repository can be found on GitHub. QWebSockets has an LGPL license, and hence can be used freely in both open source and commercial applications. Although the code is stable and already used in a number of projects, the version is still 0.9. We hope to release version 1.0 very soon, as soon as all outstanding issues have been resolved.
