OpenX Async Tags

We all want to make our site faster, google showed a few samples here: http://code.google.com/speed/articles/html5-performance.html

We use OpenX to serve ads, so, assuming browser supporting (FF3.6+), I presume we can just modify the OpenX ad tag from :

<script type='text/javascript'> ... ad codes </script>

into

<script type='text/javascript' async> ... ad codes <开发者_如何学C;/script>

Will that do the job? Is there a better way to load scripts asynchronously?

Unfortunately OpenX uses document.write to do most of its work. This means that it will attempt to write at whatever point in the flow its currently on when the script actually runs. I've tried changing the OpenX javascript snippet itself to not use document.write, but discovered that the response from OpenX often contains document.writes as well.

has anyone tried this with openx tags?
