You probably won't see a public release of any hack, at least from not f0f. Though I don't blame them, the last time they released the PS3 keys, it got them in a legal mess. Though moving forward, console companies aren't going to make the same stupid mistakes they have before with security. PS3 has been pretty locked down since 3.55 OFW and 360 has relied on HW modifications to run any sort of unsigned code. There's a whole lot of reverse-engineering that needs to go on to even begin building the homebrew base. What's worse is we/they don't know if there's any brick protections so some would be working blind.
I'm pretty sure nobody has the process all laid out. As they stated, there isn't even a base framework yet for the WiiU libraries needed to get homebrew running. I'm sure HBC would need to be re-written for the WiiU too. I wouldn't expect 1-2 people to bootstrap the entire thing, I believe that's why they put it out there to get the linux ported to the WiiU, but so far, there's been very little interest in it beyond a few people. Best thing is to get involved in the project and contribute. The sad part is they are completely right. Developing on closed systems isn't worth the time anymore, especially when having to start from the ground up with so few people to reverse engineer and code. Best example is the PS3, the homebrew on it is pretty much non-existant.
It's the same reason I bought my nVidia Shield, I can play games, stream, and even throw on some damn good emulators written on the Android OS and it works great. I can change what I need, and no walls. Vita on the other hand, you're basically locked into PSP only mode, which requires you to buy a $15-20 game every time an exploit is released.
And so far, the Vita is the first console to be unhackable as of yet.
