This modifies both the server and user driver, so it's unlikely to get in on the first try.
There are still some limitations, mainly that Wine programs will only be able to see keyboard input when a Wine program has the focus or a registered hotkey is pressed, and that simulated keystrokes from Wine programs will only work within Wine. This means that synergy will probably still not work, and it limits what AHK scripts can do. Neither of those limitations can be fixed.
