Easier Sitemaps with Movable Type

It seems that Niall Kennedy has also posted a way to setup Google Sitemaps on a Movable Type blog. His method is much simpler actually, though it doesn't currently have a way to do more than Indivudual pages. Maybe I will modify my way so it just uses that single XML file. When I first read the protocol specs, I thought that the XML files had to be gzipped, but I guess thats not a requirement. So, there is no real need to use Googles python script to zip the files up.
