@the_stegman: Not effortlessly, also the fact that she could dodge bullets at all is up for debate I think. Ultraviolet was done by the same director (Kurt Wimmer) that did Equilibrium, and Violet's fighting style was supposed to be an advanced vision of the Gun Kata in that movie. Hence, she may have been dodging bullets -- or she may have been following a pre-established set of movements that allowed her to avoid bullet trajectories and patterns.
That could also just be bulls*** since it was never technically confirmed in the film at all.
@joygirl: Your theory makes sense, as she does seem to very carefully map which gunman is where before going into action..but still, she does it, and makes it look easy, I don't see how she can't do the same with aeon.
@the_stegman: True. The only x-factor may be that the fighting style may or may not incorporate the trajectories of more skilled gunmen. Aeon also had dramatically better stealth/prep skills -- Violet, at her preppiest, was all like "get a bunch of guns and walk in the front door."
