Can't get it to work. But http://matsemann.com works. I think the difference is that my domain works even without a "Host" header.

Edit: Not quite correct that it works. My domain responds with a different dummy-page in IE 1.5. I get the same dummy-page with curl

  curl http://matsemann.com -i --http1.0 -v -H 'Host:'

Difference being it's served as 200, while same command for example.com with no host gives 404.

I think the web is just broken without host headers, as too much is running on the same ips / through routers before touching the real underlying page.
