I don't think you can with anything. It's locked.
FWIW, I only went with PT because I got one for like $200. Not a bad price considering it works. Everyone is crying about updates... it's not like it just stops working one day. It'll do everything it does today for as long as the hardware lasts. There's not a whole lot more that could've been added.
On the other side of the issue, I also hope someone tells Charles to **** off because it's absolutely stupid not releasing the source at this point.
