In the simple case, yes, I could just add the event when I create the
DOM elements.
However, my current project (Ruby on Rails with jQuery) does a lot of
AJAX calls to pull in new bits of HTML. If I want to register for
events for those DOM elements, it's easy with jQuery.live.
jQuery has two ways to register for events
$("selector").event(function (){}...) <--- "selector" must exist
and $("selector").live('event', function(){}...) <-- "selector" can
exist in the future, doesn't have to now
It seemed to me that MochiKit.Signal.connect might be a more
consistant way (aka: One Way To Do It) to do this, if the source
didn't have to exist at time of connect.

Thanks. I've seen mochikit on Github (and +2 for me: I've seen lots of
activity lately, I think partially due to the Github move)

That's what I'm thinking, actually: some kind of
MochiKit.BetterSignal.connect that :
(Python looking pseudo code ahead)
if src exists:
MochiKit.Signal.connect(src....)
else:
# add it to some list of DOM elements we are waiting for, and when
the DOM changes we look for it
That with some selector support from MochiKit.Selector might be get me
where I want to go.
Maybe I'll throw a few experiments together and push it to a GitHub
repo. (I'll let the list know)
Hope this helps,
