How about just connecting to the valueChanged() slot and if you detect that 
the value is above your "pseudo maximum" just reset the value back down to 
that pseudo maximum. It might work, not sure. Since screen redraws are 
deferred this shouldn't generate any flicker (in theory).

If it was my UI I'd be careful to provide the user with some feedback about 
where these limits are otherwise it's going to be pretty confusing having 
sliders "stuck" halfway up..
