Wow. This could come in handy for the already insane javascript, canvas, html5 space shooting game I am working on, especially if it is high performance.
My employer have insane plans of making an open source MMO that's a hybird of EVE Online and Subspace that start with my game as a prototype.
Seriously, I must have the best programming job, ever!
Please look through the mailing list and github. There are at least 5 of these in the works. Off the top of my head: express, vroom, gateway, node-router.
have you checked out express? Its not fully baked yet, in fact I am working on a fork that uses mustache.js for the rendering. Express puts a nice "sinatra"-esque DSL on top of node.js
