Hi. I have installed my Forth-like language in the Linux kernel as a kernel thread. I suspect this could have many interesting synergies with rtlinux. What I have on the matter is in ftp://linux01.gwdg.de/pub/cLIeNUX/interim with H3rL in the filename. The programming language is in the same dir with H3sm in the filenames.
