This is a project to provide police event mapping and statistics for the citizens of San Antonio.
This project is meant to provide citizens with data to enable them to better watch their neighborhoods.
It was created after reading national best places to live rankings for cities.  San Antonio was hindered by a nationally high ranking property theft rate.

Project Name Ideas: 

   * Nicolas
     * Means "Victory of the People"
     * Refers to: St Nicolas of Myra; protector from theft and more generally protector of the innocent

I got the crazy idea that the project could be released as a Puppy / DSL linux or #! Linux distro
  A debian or ubuntu compatible distro would be ideal, a tiny linux is very seductive.

    1) Code Updates could be pushed to the nodes
    2) A compute engine can be installed and used for grid operations (There goes the dream of tiny)
       MOsix, OpenMosix, Rocks are all compute engines
       SaltStack might be ideal, hacking a new setup with zeromq might be worth the effort.
    3) Volunteers can run the distro in a vm maintaining their own computers and volunteering compute time.

I spent today looking into GIS shapefile utils
