I'm in the early planning stages of doing something somewhat similar for motorcycle riders (which I am one), you feed it your commute route, typical times and it then sends you a summary of the next days commute (or ride) including interpreting the forecast in the context of a motorcycle (i.e. gust delta against base wind speed, temps below 0 in the preceeding 12hrs, estimated windchill at 40mph, 50mph, 60mph and suggested clothing - plus the ability to set alerts for particulary directions of wind etc).
I've zero interest in commercialising it, I'm building it to play with some technologies I want to learn and because it beats anything I've got currently which is mostly just remembering to check the temperature/wind direction for the next day.
