We had a client project, a Rails 2 app, that needed some cleanup around JavaScript and CSS management. They were using both Sprockets 1 and Jammit, as well as a bunch of plugins and gems to help make all this work together. They had a set of problems that the Rails 3.1 Asset Pipeline solved. But due to gem dependencies we couldn't go to Rails 3 yet.
How hard could it be to put Sprockets 2 and the Asset Pipeline into a Rails 2 app?
