Dritz has been working on one for a while for the NA page. There is another thread that has his links for testings to use. But because they are only testings, they are constantly being updated. If you want an Rss feed, then try looking in that other thread.
I don't recommend the php one but for some reason I put it up all the time. Since I'm using DOM instead of regexp to extract info I run into a few problems with the script but in the end it spits out the right xml feed. I could turn error reporting off in the script but I wouldn't be able to catch any serious errors.
I'm not to sure how that Coranto plugin would work but I don't see it being that complicated and would be a big boon to the site.
