Adding adsense to feeds

Is it possible to add adsense into existing vbulletin feeds without a need to have feedburner account ?

Even if require a feedburner account is there a way we can mark all existing external.php links to new feedburner accounts

Is anyone been able to run adsense for feeds for vbulletin based forums, please share the URL via post/pm.

Thank You.
