If you want to betatest it, please let me know and I will make sure you get a free upgrade. I know they are looking for betatesters.
Neither awstat or Google's Webmaster tools help you check your rankings. They are very useful but not for ranking tracking.
Really, if nobody has tried it, http://www.keywordenvy.com has a free version that will check your ranking for you every day, and make a graph of the rankings. You can do this for up to 15 keywords and they support Google (many countries), Yahoo (many countries), MSN, Live, Ask, Baidu, and a few others. The homepage tool lets you search for free too, and also gives you keyword suggestions. I honestly think you'll be amazed when you try it.
