This is something of a solved problem for many of the major javascript frameworks. Sproutcore (just to pick an older example I'm familiar with) has had this licked since 2008; you put all your DOM-upating code in your view update calls, and Sproutcore pipelines the calls. I'm sure most of the other JS MVC frameworks have similar solutions.
