I can't tell if any of this gives you more access than the normal http admin interface.
Now if you could use to allow firmware downgrades when the installed firmware doesn't, that would be useful too. I disabled updates on mine at a version that already allows it. I bought it a few weeks ago but luckily it didn't come with the latest "I don't like your ink chip" firmware.
Sometimes a hack is just cool because it’s a hack.
