As well as supporting a comprehensive set of Lisp features and Arduino extensions, uLisp for the ESP8266 includes wi-fi networking commands to allow you to take advantage of the ESP8266's wi-fi capabilities with the convenience of uLisp's compact syntax.
For more information, examples, and recommended boards, see Lisp for the ESP8266.
I'd welcome feedback in the uLisp forum from the ESP8266 community, especially on the wi-fi features.
