Libre software in general, real-time Linux kernel variants and standard Linux kernels in particular are already widely used for control and automation
projects, whether they are embedded or run on desktop computers. The Internet provides a valuable means for the evolution of such projects, and their
pioneers guide the development. However, there is a lot of parallel effort going on, and also lot of complementary development in these projects (See
a short list;); each single project, however, would not reach a critical mass for a breakthrough and wide acceptance in industry.
