Is there a moreover.com-style service for weather? I want to be able to easily download the local temperature every 15 minutes (without having to parse a webpage) so I can instruct my air condtioner to turn on or off (X10 switches rule).

I also want to find a lightweight program for my Windows-box that can use my modem every 15 minutes to see if there’s a stutter tone on the line (indicating voicemail), so I can automatically send a page to myself letting me know to check my phone.
