MapPoint and Virtual Earth - Determining the 'outside polygon'   

I'm not entirely sure how to phrase this question because I probably don't 
have the right words to describe it.

I'm working on a Virtual Earth implementation where I need to draw a 
ShapeLayer over a particular area of the map.

I'm using TIGER data, which has been formatted down into linedata (lats and 
longs), which I can parse, and display on the map.

However the polygon data is by street level, so I end up with 4,303 
different Shapes to define a single neighborhood of streets.

Does anyone know a quick and easy way to take these LatLong Points, and 
determine the maximum polygon to display?  I'd love to be able to add a 
single ShapeLayer to the map, instead of 4,303 (which tends to render slowly 
and look pretty bad).

Any direction you could point me in would be great!

Thanks!

// Dave
