js/css resource serving in python apps with Fanstatic

I've just been checking out Fanstatic, a resource publishing/static file serving solution for wsgi python apps. I've been contemplating something like this as our javascript and css dependencies are getting more complex. It would also be useful to have some form of automatic cache invalidation so users don't have to do a special browser refresh when we update our applications.

It's easy to set up with CherryPy

from fanstatic import Fanstatic

if __name__ == "__main__":

    app = cherrypy.Application(Root())
    app.wsgiapp.pipeline.append(('repoze.who', setup_auth))
    app.wsgiapp.pipeline.append(('beaker', setup_session_storage))
    app.wsgiapp.pipeline.append(('fanstatic', Fanstatic))
    cherrypy.quickstart(app, config='workbench.conf')

after that is done, you can jquery.need() in the widget/template that needs jquery, and similar for our other dependencies. Has anyone else used fantastic? What are other solutions to dependencies and serving js/css? Is there an easier and better solution? Wrapping new libraries for fanstatic looks like a bit of effort but I haven't explored it much yet.
