Description (last modified by )
The solution could be as simple as a flag, or yet another function argument, but .setup, .add, .teardown, and .remove should all have some way of knowing whether they are being called via .bind vs .live/.delegate.
I've made some attempts at inference here (view the console): http://jsfiddle.net/cowboy/f5rkz/
But that's clearly less than ideal, especially when you need to maintain a cache of elements internally, like in this example (imagine trying to make this work for both .live/.delegate AND .bind): http://benalman.com/news/2010/03/jquery-special-events/#event-delegation

Ben, I know you can patch this in. Wannadoit?

What I'm going to do first is try to implement this plugin in a way that works for both bind and live/delegate:

After that, I'll see what, if anything, needs to be done.

A reduced test case would be good. Going to bring this up in the 1.7 roadmap meeting - your input would be good, cowboy!

+0, Just need to be sure we have a use case for this (I trust ben, just want to see a use case first hand before being all "Yes yes yes")

Use handleObj.selector (in the handle hook, event.handleObj.selector) to determine whether this is a delegated event.
Do you have some examples where it would be convenient to have that info? I'm not familiar enough with the special events interface to know. For a case like jQuery.event.special.submit it's enough to know that the element handling the event isn't a form, but maybe that's the exception rather than the rule.
