I think the K mount is old enough that anyone who wants to can easily find out basic specs and build a lens. As to whether or not auto focus is easily done with it, the problem (as with all of these) isn't the mount, but figuring out how the lens interacts with the autofocus system in the camera. My guess is that Samyang has just reverse engineered this for Sony, like Sigma does for all their mounts. As to whether they ever release k mount auto focus versions, I think it probably depends more on Pentax's market share and what they think they can sell, as opposed to whether the K mount is open source or not.
