[NTLK] Newton gateway idea

I just discovered the Raspberry Pi Zero. It has slightly more power than the original Pi, but is on a "wafer thin" board and costs...drumroll...$5. A whole kit is about $30 at Adafruit at the moment. I was an Arduino and Netduino enthusiast, but now a whole Linux computer for less money than a microcontroller opens up all kinds of possibilities, like your gateway idea.

It would have a WiFi and/or LTE and/or Bluetooth radio for its upstream connectivity and act as an IP router, firewall, and application-layer proxy for various services for the Newt.

You’d configure applications on the Newt to connect to the services on the card, and configure the card to connect out to GMail, iCloud, etc (using SSL).  Configuration of the card could be via a basic web page (HTML2 over HTTP1.0) or perhaps with a dedicated app on the Newton.

The Newton would use NIE to connect to the companion board, either via serial for a “modem” card or by having the board emulate a serial or Ethernet card for PCMCIA.  A “modem” card would require minimal additional drivers (same as Jake’s WiFi card); a PCMCIA card would need to either emulate a supported serial or Ethernet card, or require a dedicated driver.

But an iPhone can support a powerful CPU, GPUs, lots of RAM and flash, LTE, WiFi, BT, GPS, etc, etc, using a ~1500mAh battery, and IIRC, AA’s are roughly that and we have 4 of them, so perhaps it’s possible?
