Problem statement :    with many a GPS based ready to use libraries available
  
                       with gps data sources from google to a-gps kind of resources
                       accessible over the internet

Opportunity : GPS plotter for desktop/laptop/tablet-pc ....using python/perl/php/java

              a ready to use gps console ...making use of readily accessible gps data
              source's accessible over the internet  or in this context ...subscription
              to gps data sources from dedicated gps feeds over mobile networks from
              sources (various service providers with ready to use constellation of 
              satellites being available) etc.
