Dashboard widget exporting/importing

Hey guys, I just thought of something interesting that would be a nice to have. Rather than exporting the entire dashboard to xml it would be neat to export a widget.. The same with importing... when adding a new widget one of the options would be widget from xml. That way people could post sample/ templates of a single widget and others can manipulate the data / import it in to their dashboard.

The thought came to me today as had just got done adding two graphs to a dashboard but am now export to xml to add 20+ datapoints to each graph.
