It is kind of very hard to work with a platform that has very tight memory management, while memory management doesn't have any detailed documentation, and the whole Zorro platform is closed, no direct access to how data structures are organized, which makes it very hard to work with other utilities being used by other platforms like Python... and synchronizing between them for HFT, is a very serious challenge. I think the amount of time invested in developing the platform in relation to how many people have the ability to advance faster, without having too many challenges with interfacing different platforms together, is a serious limit on the amount of users that can take of the advantages of Zorro Project.
