QNX Publishes Neutrino Source Code and Opens Development Process
http://www.qnx.com/news/pr_2471_1.html"Not only can developers view the QNX Neutrino source code, but they can improve, modify, or extend that code for their own purposes or for the QNX community at large. They can then choose to offer back those changes to QNX Software Systems and the QNX development community or to keep their modifications private and proprietary."
