That's why I did a little hacking and extract the essentials needed to embed widgets like Newsreel in pages/sites built on top of something else than Blogger.
This is actually a technique that could be easily applied to other Blogger widgets as well.
I wrote the code for an HTML page that can work standalone. Simply take the following code and paste it inside a new file, save that file and open it in your browser. You'll get the Blogger Newsreel widget embedded in a page other than the one served by Blogger.
Of course, as any other hack, this might not work if Google decides to change something. So do use it at your own risk.

Update: a test page has been uploaded at http://blog.tremend.ro/wp-content/uploads/2007/02/upload/test-newsreel.htm
Update2: to modify the news you wish to see inside your widget, use the script below. In the line var expression = "blog";, just replace the "blog" with anything you wish from news.google.com
var expression = "blog";
