Home · esp8266/esp8266-wiki Wiki
The ESP8266 is a very cheap microcontroller-onna-board with proper wireless networking and a TCP/IP stack. Most people seem to hook it up to another microcontroller, but you can run code on the ESP8266 itself; this site has cross-development tools and documentation. (Although it's only IPv4 at the moment, so it wouldn't be very useful for sensor apps on my home network as-is.)

"KeySweeper is a stealthy Arduino-based device, camouflaged as a functioning USB wall charger, that wirelessly and passively sniffs, decrypts, logs and reports back (over GSM) all keystrokes from any Microsoft wireless keyboard in the vicinity." So that's three reasons why I won't be buying a Microsoft wireless keyboard, then.
