Yeah, Lua and Erlang in particular seem better suited to this role. Erlang's whole model is fundamentally event-driven, and Lua is remarkably similar to Javascript, only without the design errors made permanent, and with a better JIT compiler. Javascript's already closely tied to the web, though, and it gets plenty of word-of-mouth since web developers already know it. That will probably beat any technical advantage.
