I hope that Rails has the weight to push these kind of changes into Rack.
I think that Rack is one of the best things that happened to the Ruby web-application community, and I'm a little sad that Rails is getting a "vendor specific" implementation of what should be a wide reaching feature. As you said at @scotruby though, Rails is in a unique position to direct the development on both sides, front and back end of development. (I believe in Scotland you were referring specifically to pushing backend queue implementors to meet the new Rails queueing API.)
I'm looking forward to seeing people building upon this for common use-cases such as streaming reports, CSV exports etc to clients, as well as the more `fun` stuff about live browser reloading (which guard-reload implements very nicely, actually, using a different technique)
And, I think it's fair to say that using a queue, and having a queue consumer (again, I think you demo'ed that in Scotland) isn't such a bad solution, at least as a more experienced developer I appreciate the moving parts, and it doesn't distract me too much from solving the problem at hand, and - most importantly it works.
That all said, I think this is a valuable change, and I thank you for your time in making it work, and coming up with an interesting test-case.
For what it's worth, my last word would be about a post on HN a few days ago, about streaming JPEGs, multi-frame streams often (apparently.) used for IP camera livestreams, that's quite an interesting case which could lead to this controller technique being used to do live image previews without page reloads in Rails with AJAX image upload.
