Create a PWWS (Personal Weather Web Site)
Collect the information from the site and allow PWS owners to create a PWWS (Personal Weather Web Site).
Basic free subscription would be stationname.wunderground.com domain based and no possibility to customize, ads supported.
Pro (pay $) subscription stationname.wunderground.com domain plus templates and customization, extended API usage, no ads.
Premium (pay $$) subscription, can run on own domain (via dns cname redirect) plus premium or custom templates, no ads, unlimited usage for the API.
This is an interesting idea.
At the moment, we're going to start with a PWS dashboard: http://help.wunderground.com/forums/176918-personal-weather-stations/suggestions/3395744-real-time-dashboard
