Darren, great to hear, about the pineapple core project.
I've currently already got a pi2 I'm using as my side workhorse for the nano. my goal was exactly that.
Let the pi take on the majority of the work. The more i can pipe through the better. So far I've got the pi connected to the nano both set to auto ssh to my server so i can control everything on a separate tunnel for now while testing and configuring it all, both connecting separately at the moment. I've noticed the nano not always regain the wlan2 connection after sending a reboot sometimes, so i took the safe road and made sure both have a connection as a failsafe.
So i can't wait to see what you guys come up with.
So far I've got the Pi2 configured with Rasp Debain, with the Kali Rasp repo's of tools installed. i feel that is a little safer if planning on deploying then the Kali Raspberry version.
