The way Backbone is structured (or this could be my limited understanding of it), you have to hack it at a very low level to get something like this going. Some people may have concerns with respect to Backbone.js upgrades breaking this. However, if you have test coverage in your app, upgrading backbone.js should not be an issue. It has worked well for us from 0.3.3 through 0.5.3 for example.
