Just noticed I forgot to reply to that. The main difference is that we got a lot of stuff working *before* getting f0f's help. I think by the point we got access to all the private Wii U hacking stuff, we already had dumped the GamePad flash, reverse engineered all the Wi-Fi stuff, and had audio and input streaming working. It also took us only a week or so to get to that point. Compare that to Maxternal and friends building on f0f discoveries and taking months to implement a (fairly trivial) race attack.
