Is it feasible to load 'code logic' dynamically in iOS app?

Question

I am looking at this WWDC session: Integrating JavaScript into Native Apps

My understanding is that this is a bridge between Obj-C and javascript, that allows calling javascript code from Obj-C and vice versa. I am wondering, does this mean I can dynamically load my 'code logic' from server in javascript, like in web applications? How should I structure my code so that a large part of my code is in javascript (Obj-C is still needed to drive the js code, of course).

If this is feasible, then deploying changes to iOS projects would no longer be such a painful experience(waiting for review and user upgrade,etc), development could be more agile. I know some teams use phonegap and similar frameworks just to get this advantage, but those solutions doesn't get the most of iOS native UI widgets/features.

If both data and logic can be loaded from server, and the Obj-c part is just the (relatively) stable skeleton code, then iOS apps become web apps without HTML (consider the app a customized web browser which loads code and data from server).

So my question is: how feasible is this? How should I split the code between Obj-C and js to make this as flexible as possible?
