I have to admit I was thinking this was the more classic "penetrate networks" use of the term "hacking" as opposed to the modern "creatively overcoming limitations" usage. Took a moments of browsing to offset the confusion.

Kali is just a Linux distro. Most/all tools in Kali are available in other distros, and not just the 'hacking' distros. In other words, you can still run Metasploit and suchlike on something like Plasma Mobile.

Well, this thing can run Ubuntu Touch apps, and it may even be able to run Sailfish and Nemo apps later on...

Ubuntu Touch is the big one though, I'd love to see more devices compatible with it. Some industrious fellow out there is probably willing to port most of the python crap in Kali to something more useful, agile, portable, and compatible with Ubuntu Touch, if something like that isn't already going on.
