google maps etc

i've been continuing poc on the idea to use google maps to plot houses for sale. not an original idea it turns out as theres a ssimilar thing done in the us with craigslist.

obstacles so far have been post office being nazi's and owning the copyright to postcodes. but i've written a really simple screenscraper that scrapes google maps to get the latitude and longitude values. postcodes are important not for the user but for estate agents to be able to add a property.
i expect users to just search by place names.

so far i've got this:
1) screenscraper
2) list of uk towns and cities and their lat and long values
3) thought about how the ui would work
4) created a basic generic da class
