I'm sure the bandwidth of the electron beam is many times greater than 
what you could achieve with a laser.  Unless you get really exotic, 
displacing the laser spot would be through mechanical means, wouldn't it?

I guess the advantage is you can project the beam on a wall or 
something, but it seems like a lot of work to get an inferior result.
