On a Japanese keyboard this just change the keyboard input mode
every second... imagine that your keyboard layout change every second!

Currently the lock sync on the server is done sending a specific
scancode, the problem is that on the guest this scancode is not
associated with the lock function.

What does it means "keep the locks on your keyboard"? You mean never change
the client locks even if out of sync?
Yes, idea of status bar is fine, it's surely implemented by Bochs, I think 
also in VMWare player.
