How to burn DVD to multiple drives?

[Matt Chapman <Matt@ChapmanMedia.com>]

Can anyone tell me how to burn a single DVD ISO to multiple DVD-burners 
on my system at the same time? This would result in multiple identical 
discs.
I'm thinking that if there isn't a way built into growisofs or 
something  like it, perhaps there is a way to make the standard output 
multiple devices for use with mkisofs options?
Thanks!
