You refer to the size of the RPi SD card and I wanted to point out that RPi is a real linux system and you can easily mount USB cards or even terabyte external hard drives. In general programming cases it probably makes sense to install J (as well as ~temp ~user etc) on a USB stick and reservce the SD card for the essential service of boot and OS. For embedded stuff (like a robot controller) it makes sense to put it all on the SD card.
