From my memory 5ms delay is about 1 or two meters of sound. So instead of 
hearing the direct sound from the guitarists amp 5 meters away, they hear the 
indirect headphone sound of it "2 meters away". I think they can cope with 
that.

And running an analog signal through a lot of RC-parts with all the phase 
shifting is probably not that zero-latency as you might think either.

And for the crowd its the less a problem, the bigger the crowd and venue is, 
the might here a slight effect when they are really close to the stage and the 
PA isn't that loud so they hear both the singer original and trough PA.
For other instruments: Drum sound is to short to figure out the phasing, 
guitars have the phaser already as an effect, keys are not that loud on stage. 
So the effects you hear are to slight to hear them when you are actually there 
to listen to the music.

All in all the question isn't whether going digital is ready for live usage. 
It is used for that already by _lots_ of productions.
The question is whether custom-made Linux rigs are ready for live usage. And 
there the answers are a bit more spread.
