Stitch over asset pipeline

I’m wondering if anybody is using Stitch (
http://alexmaccaw.co.uk/posts/2011/06/30/rails_js_packaging.html) over
the
sprockets pipeline?
Sounds like the solution that should have been introduced over
sprockets.
What I’m wondering is if we would be also able to use NPM to import
local
commonjs packages to our rails apps?
Then, I guess, use a compressor like the dojo one? that interprets
commonjs
dependencies (instead of blindly compressing everything in a directory
tree)?
