I have an old laptop with some spare room inside it. The laptop itself is not much, but it works and I don't really want to replace it. I also have a Raspberry Pi 2.
What I would really love to do is house the raspberry pi inside the casing of the laptop and be able to SSH to it, move files to it, etc. and essentially treat it as a second computer. I can not use the Ethernet port to access the Pi because of space constraints and because I would like to keep the laptop's Ethernet port free. Is there an alternative way to communicate with the Raspberry Pi that will allow me to access a fileshare (either hosted on the RPi or on the laptop) and also log in to the RPi?
