There was some discussion on distcc maillist over year ago, but it 
ends to nothing. As far as I understand it is too difficult to 
implement without overhead impact.

Really, not every application, but only tiny subset of them. 
Absolute majority of applications do not set all *FLAGS on their 
own, they just append flags they need to the system-wide flags, in 
other words they just reuse external *FLAGS. Needless to say that 
almost none applications detect local CPU-related optimization 
flags.

MPlayer is very special in this case: it sets all of them in its own 
way, it provides benefit of fine tuning optimization, but it should 
take responsibility for side-effects as well.
