Actually, it is quite easy to do AJAX with Habari.
First, write your JavaScript and include it using a hook in the theme.
For examples of this, just check out the -extras repository.
Have the AJAX request sent to example.com/habari/ajax/foobar. (You can
generate this URL with URL::get('ajax', array('context' => 'foobar');)
Then, in your function, just implement the ajax_foobar action. (Make a
method named action_ajax_foobar).
Whatever you do in that function (and only what you do in that
function) will be called when the request is sent. No hacking needed,
everything can be contained in your plugin file.
