For instance, there's an RT-PREEMPT branch for the BeagleBone kernel, done on customer request, and it looks like it has next to no uptake and has fallen behind quickly. There is a huge potential industrial demand for FOSS RT on embedded (i.e. beyond Wind River, QNX et al), like from automotive, traffic control, medical - but my gut feeling is it will remain 'potential' until the stakeholders come around to back one of the efforts underway such that tangible results on a predictable timeline are likely. It might also be a bit of a sales problem of some of those projects. Until this shakes out I think the order of the day is to keep all options open.
