This is the most radical part of my rebuild; all of the other aspects have been touched on before in the previous iteration. However the introduction of a second Pi is completely new.

The two Pi's; one Model B and a B+, will be directly connected to each other with a small Ethernet cable; The Pi's do not require a crossover cable so a standard CAT5 will do.

Over this Miniature LAN the Output Pi(B+) will have all have all the media stored one memory cards/HDD, and will sit and monitor a websocket for commands to play videos from the Touchscreen Pi (B). The Touchscreen Pi will use a webserver to host the GUI and send any selected commands to the Output Pi. The touchscreen Pi will have Network File Sharing (NFS) Access to the Output Pi so it can manage playlist and also play videos itself if necessary.

So far here is how i hope to configure them:

Touchscreen Pi

• Static IP
• Tornado Web Server (handle GUI and sending play commands to the Output Pi
• NFS Client (for accessing videos from the other Pi when no output device connected)
• Wifi Dongle connected and bridged to the LAN (should allow both Pis internet access for playing youtube vids and more)
• VNC Server (For programming over the network from my Netbook)

Output Pi

• Static IP
• Web Client (for reading play commands from the web socket)
• NFS Server (for allowing access to files to the Touchscreen pi)
• VNC Server (For programming over the network from my Netbook)
