Hi Kurt, I found your project on a Qt forum post through a Google search, and in the forum post you requested that we leave a comment here if we use your project. Well, here you go. :-) I do not need to make heavy usage of WebSockets. I am simply using it to connect to the Leap Motion controller's local leapd process. I needed something cross-platform and preferably Qt and preferably Qt 5. It is working fine. You see, even though Leap has a C++ API, I ran into build and runtime issues using on Windows and Linux, respectively. I learned about leap.js and the WebSockets API, and now I use that to make a cross-platform solution. See http://www.shotcut.org/ for my project. I have listed your project on the Credits page.
