Let me know if you are interested in any kind of commercialization of my rail. I am willing to provide both the hardware design and my software for free, and will continue to develop my software (as Open Source). This rail can compete favorably with such commercial devices as Cognysis StackShot at a substantially lower price point: Cognysis is sold for 550$ USD, while the cost to build my rail is around 150$. My rail can be commercialized as a DIY kit (say, for 100-150$, without the Velbon Super Mag Slider), or as a ready to use product (say, for 300-350$).
