DVD Burner Farm

This may be a bit off topic but maybe someone here knows the answer to
my question. I'm looking at putting together a system that will burn 50
DVDs at a time. I'd like to use 16x Burners such as the Pioneer
http://www.pioneeraus.com.au/computer/dvdwriters/dvr108/ I would like to
be able to send the DVD burner farm an iso image via a network
connection or firewire perhaps. Of course I'd like the system to be
Linux based but can't be too fussy. I've seen duplicators like this
around http://www.americal.com/pg/pioneer-16x-dvd-duplicators.html#nine
however as far as I can tell they all need to have a source DVD first.
Has anyone got any thoughts on this? How do the big guys do it?
Jim
