Mapping actions from postcode data

If you have UK postcode data for your actions, how can you display supporter actions on a map?

One list member suggested making a google map from a dynamic feed using this process:

Another suggestion was using Google Fusion Tables. This example map of MP votes uses the the TheyWorkForYou API to get geo data (lat/long) for constituences, but Google Fusion tables will map postcodes in the same way.

Finally – the  Mapalist service creates free maps from postcode data in a Google spreadsheet. You can keep this updated with new actions as they come in if you can set up an XML or Google Doc feed.
