That's very good to hear, snas, that there's going to be a news company using the iliad.
Actually, you can't run applications from contentlister on a factory-new iliad. If you want to run shellscripts (.sh) then you need the developer package enabling it. You can request it here:

But be aware that you are doing this on your own risk (i.e. if you manage to delete something vital using a shell script, it's not iRex fault)
Btw: On your page you are writing about updating using wlan. I'd really love to know if you are going to distribute it using iDS.
