[jQuery] extend

[[EMAIL PROTECTED]]

Hello.

I would like to know if it's possible to extend jQuery like that :

        // Init os
        $.os = $.os || {};
        $.extend($.os,
        {
                version         : 'foo',
                event           : function(event){  return event.xxx; }
                core            : false
        });

        // Play with os
        console.log( 'os: ' + $.os.version );


I'm unabble to add some functions to the $.os object and get 'this'
element :

        // Extend os
        $.extend($.os,
        {
                fix : function(){ this.html( 'os on: ' + this.tagName ); }
        });

I would like to call it like that :
$('body').os.fix()
$.os.event()

Does anybody know what to do ?
I really need something like that to make my code simple to
understand.

Thanks
