Is is not just a case of replacing jQuery(document) with jQuery
(this.context) in .live() and .die() functions?
This works when the context is supplied as an element, eg:
var elem = $('#my-buttons')[0];
$(':button', elem).live('click', ...);
but not as a selector or another jQuery object:
$(':button', '#my-buttons').live('click', ...);
Although, I think this is acceptable behaviour, as you wouldn't want
to bind to the context unless you were absolutely sure it existed and
remained static.
Anyway I'm probably overlooking some bigger picture here.
