I have a few different scenarios I'm wondering if I could use this for:

1. Have individuals sign up on a simple landing page for snow-shoveling services and place their location on the map? Maybe the map could be private so only the webmaster could view the user submitted locations?

2. A marketplace similar to Craigslist where the seller could input their general location without specifying their exact address? Or maybe they could submit a location they'd be willing to meet to exchange an item?

3. Could this be used as a virtual tour, say of the history of a town?

Thanks.
