it is cool. the idea of the linux OS and the program on the bare metal of the arduino running concurrently is interesting. i wonder if there is any way to communicate between the two (i.e., shared memory or something).

Yeah, it reminds me of my NeXT Cube and mounting a spare '030 motherboard to use as a print server...

You might look into the Arduino Yún as well. It's a different design target, with different capabilities and lower performance since it is a 2013 design... but they're widely available. (You would have to wait until September for the UDOO Neo.)

arduino.cc website wrote:The Arduino Yún is a microcontroller board based on the ATmega32u4 (datasheet) and the Atheros AR9331. The Atheros processor supports a Linux distribution based on OpenWrt named OpenWrt-Yun. The board has built-in Ethernet and WiFi support, a USB-A port, micro-SD card slot, 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, an ICSP header, and a 3 reset buttons.

The Yún distinguishes itself from other Arduino boards in that it can communicate with the Linux distribution onboard, offering a powerful networked computer with the ease of Arduino. In addition to Linux commands like cURL, you can write your own shell and python scripts for robust interactions.

The Yún is similar to the Leonardo in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Yún to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port.

The Bridge library facilitates communication between the two processors, giving Arduino sketches the ability to run shell scripts, communicate with network interfaces, and receive information from the AR9331 processor. The USB host, network interfaces and SD card are not connected to the 32U4, but the AR9331, and the Bridge library also enables the Arduino to interface with those peripherals.

that is indeed very cool. i had heard of it but never really understood what it was. thanks for sharing!
