If you want a linux alternative, try pywws at http://code.google.com/p/pywws/
. I have been using this on a Linksys NSLU2 for about 4 years, and I am in the process of sorting it out on my RPi (works fine, but USB package drops occasionally). This series of python scripts logs the weatherstation data, and gives you the ability to generate text files/graphs which can be uploaded to a website http://thesutherlands.co.uk/weather.php
(also updates WeatherUnderground, twitter http://www.twitter.com/key_weather
, MetOffice accounts too). Someone else on these forums has described how to get it installed, so do a quick search if you are interested.
