Remote development over WiFi

There’s a fascinating option for the JeeNode Zero, called the esp-link by Thorsten von Eicken. He also created a little board with a switching regulator, the ESP8266, and an FTDI header, and calls that a “WiFi-link”. The result is essentially like a “BUB/SerPlus over WiFi”: The esp-link firmware turns the ESP8266 into a transparent bridge from WiFi to FTDI serial, with the ability to control the DTR and RTS signals (RTS reuses the CTS pin next to GND for this purpose, just like the modified BUB and the SerPlus).
