Not unless your script opens it and it's in the same domain as the page
containing your script. That's a security feature -- otherwise, people
could rewrite other sites' pages.

Instead of depending on the site, why not test the user's capabilities
using JS and handle him according to the outcome? Your Skype button code
includes this:
<script type="text/javascript"
src="http://download.skype.com/share/skypebuttons/js/skypeCheck.js">
</script>
You might want to have a look to see how they do it. Also, have you
checked to see what information might be available for developers from
Google and MSN?
