I'd rather see the node-servo version ;)

As far as I understand, Servo will come with a WebKit embedding API, so the possibilities are pretty much endless.

Servo uses spidermonkey as JS engine, so I don't think it brings anything in a "run js headless" context.

Although it's possible that some of the changes required to integrate Spidermonkey and Servo might make the former easier to embed?

True, but mostly because writing a JS engine from scratch is hard although not impossible.
