I'm assuming yes, but just wondering if there is any difference having the "master" off-camera.


Thanks for your help!

No, a Cybersync triggered Canon 580EX will not cause a Canon 430EX in slave mode to fire. You would need another Cybersync reciever for the second flash (or else an optical slave may work under certain circumstnaces).
