Just 4 wires to wire up (although a more powerful 3.3v regulator may be needed). It seems like adding support to Espruino should be trivial, and it would be able to coexist with the CC3000 driver too.
Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.
Just to add: I've now ordered a few ESP8266 boards.
There seems to be some documentation here as well: http://www.electrodragon.com/w/Wi07c
