So, I was looking at the manual (while I was working on a project), when I noticed the GPIO setup.

I just had the idea that if anyone owned 2 GPIO-capable devices, then couldn't that allow for networking? Sure, that does have a few issues:

• only 6 bits at a time (pCHIP has 6, but CHIP and RPI have 7)
• only 2 devices can be connected

But couldn't that work? Maybe Pong could work, as well as turn-based games.
If anyone has access to 2 of these devices, hopefully you can help me (I only have 1 RPI).
