Maybe i am missing list posts? I have no post from clarence regarding a 
modifier key.

Yes, they work very fine. I still had an issue with my driver as the linux 
event system only reports changes. So the accelerations i forwarded to enigma 
sometimes were 0 if they didn't change from the last event. That's og course
wrong.

In the meantime after some fixes and a little bit fine tunig in the enigma 
driver as well as the sticks firmware, enigma plays really smooth using the 
tiltstick.

Who's the main guy currently behind enigma? I'd like to donate a tiltstick
(only one since it's an evening work to build one manually).

I have done everything inside client.cc, but as it's basically a call from the 
existing routines to two of my own ones, it should be a matter of minutes to 
move to code to any other location inside the game.
