Using parameters in the FeathersJS service path?

I'm using feathersjs "0.4.0". (http://feathersjs.com/) I'd like to define the path for a feathersjs service using path :param place holders. Is this possible? I've been unable to get this to work with feathersjs. It works as a standard route in express.

app.use('/api/actions/:actionId/likes/:likeId?', likesService);
