When I first suggested to Frode to write a tuner library, it was for hiding tuner frequency to channel mappings, not to hide any OS dependancies. If we want to abstract away the OS dependant parts (the ioctls), and write a new API, I suggest we follow the Video4Linux Version 2 API (V4L2). Bill, who devised it, gave it alot of thought and was happy with a *BSD implementation.
