Mulitple burners are no problem, the only problem is to keep track of 
disc A, disc B, ... if you want to do 30 each of them.

This is what I did for my choir.

$ ls -l

-rw-r--r-- 1 karl users     2118 Mar 30  2005 b.toc
-rwxr-xr-x 1 karl users      170 May 14  2005 run
$ cat run
#!/bin/sh

devf=$1
devn=$2
toc=$3

eject -t $devf
cdrdao write -n --driver generic-mmc --device $devn --speed 8 $toc
eject $devf
dtmfdial 1234 # just to get my attention
$

Then I start two xterms and run

 for i in `seq 1 30`; do ./run /dev/hdc ATA:1,0,0 a.toc; done

 for i in `seq 1 30`; do ./run /dev/scd0 1,4,0 b.toc; done

Hälsningar,
