I read the doucmentation for machinkit http://static.mah.priv.at/public/portable-realtime-API-talk/osadl-rtapi.pdf and on page five there is "motion queue" between g-code interpreter and trajectory.
I implemented a stepper driver on external device and with a receive fifo on this there will be a queue between kinematics and interpolator. The nice thing with this is stepper driver could run smoothly on it's own clock and only slowly adapt to kinematics clock. Basically motion could run without noise even though there is jitter on received data.
