I know it's a big no no to call an executable from a mod, but I know Blizzard allows a mod that controls Winamp from within WoW (that uses an exe) and I was wondering if it's possible to write something that could display the current local temperature, maybe in a minimap bubble.
Heck, it may be possible to do even without an executable, I'm not sure. Some weather modules I've had for my desktop can parse the info from the National Weather Service and I'm not sure the protocols involved to do that , so I'm hoping it's possible to extract that data without actually having an executable.
The mod could parse in selectable increments by the user (say every 5 or 10 mins) so constant parsing would not hurt WoW's performance or overload the NWS (in fact, I believe you can only parse every so often from the NWS).
Geniuses, please apply !
