This is a very interesting technique. I love seeing new ideas for how middleware can be used. This suites the online/offline problem very well. I didn't use this for my bulk/batch API personally because I needed to better tune performance, but I can see how this could be very useful. Thanks, Ryan.
Great screencast, Ryan. I have been toying around with Backbone and Ember. I hope you do a screencast on ember. I think it is interesting to contrast the end user development strategies between Ember and Backbone. Both libraries offer similar benefits, but are used in pretty different ways.
I like backbone, but being a Rails guy, I think I prefer the approach Ember takes.
