No, generally you feel the changing of the impuls which is also true while 
moving with only little less than light speed. And as you can`t determine the 
"real" absolute speed you have to assume that all of us are moving with 
~c... ;-)

But with not to long latencies you can compensate that.
I remember doing a powerpoint-presentation once where the slide-changes had to 
come on-beat of the music while not being synchronised with midi etc. After 
the first tests I actually recognised the latency of evil MS and compensated 
it with clicking the button earlier...

As far as my knowledge goes: more than 20ms are only usable for slow 


There is a theory which states that if ever anyone discovers exactly what the 
Universe is for and why it is here, it will instantly disappear and be 
replaced by something even more bizarre and inexplicable.

There is another theory which states that this has already happened.
