Agreed. Which is why I essentially said not to use the patch in the
comments. It's more a proof of concept than a useful hunk of code at this
point. However, if there was a mechanism for injecting some information into
the returned response that could be reacted to, I think that would be swell.
Currently, I'd have to implement such a thing on my own.

I'm going to see if I can come up with something that's more flexible and
less likely to bring out the cranky-architect. After looking through
jifty.js in detail, it looks like Jifty.update() and related functions
really ought to be refactored as a Jifty.Update class (probably with a
better name than that) with parts that could be used separately and would be
more extensible. I could see Ajax and PubSub being extensions of some base
with the potential of the application further extending them and then
setting:

framework:
  javascript:
    ajax_update_class: MyApp.AjaxUpdate
    pubsub_update_class: MyApp.PubSubUpdate

to make all the event handler code use a custom class instead. Just thinking
out loud...

Cheers,
Sterling
