I was thinking something along the lines of a web-hosted version of the Web IDE that actually just gave you access to the Espruino console (as if it was plugged in). With access to the console you could basically do whatever you want - and it's not really adding much in the way of overhead to Espruino itself.
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.
