Sorry for this all to basic and not helpful question... But I just find 
this *too* exiting :-)

If I understand You right, X  do now suport semitransparant windows so 
the directFB hack with transparent unfokused windows only needs a 
windowsmanager to suport it? I have been strongly beleving this was a 
directFB hack only.

I love 'fokus folows the mouse', but it needs obvius feedback for where 
fokus is. Windows decoration is not *realy* enuf, transparent windows is!

Whith aplication being able to set an opacity this have to be combined. 
An example is better then my broken english:

wm: focused window 100% opasity
wm: unfokused window 50% opasity
app: 80% opasity -> focused 80%, unfokused 40%

That sems sane, but might not nessesarly be part of the spec.
