Thanks but it's not really what I'm after - I want a script that will resume items that I've already started downloading, so I can set iCal to run the script when my off-peak download quota starts at 3am. But thanks anyway 🙂
I haven't tried this but will iTunes resume downloads if you restart it? If there are pending downloads and you quit then when you launch it again will it start downloading?
If so you could just put an alarm into iCal set to run iTunes at a given time.
