Do we really need to iterate here?

Would'nt 

    var $tags = $('.asset_tags');
    $tags.smartAutoComplete({ // options });
    $tags.bind({ // options });

do the same thing? (or even just chaining smartAutocomplete and bind

Also, awesome if we can find something else than just a class to do the lookup on (ie. $("input.asset_tags") or $("#asset_form").find("input.asset_tags");
