In the distant past I did some experimentation with getting EMC to work on Linux-Preempt. I'm interested in helping to move that forward.
I'm currently working as an intern for IBM with one of their experimental OS teams, and once I have finished that, and defended my thesis, I should have some time (and a lot of interest) in making EMC-LPRT a real thing. So, please keep me in the loop.
