I'm a bit more on the object approach as well.  I think it's a bit more 
human readable, without really all that much fluff in the big picture.

A very small multi-polygon ends up something like this:

[[[[10,10][10,20][20,20][20,15][10,10]]][[[10,10][10,20][20,20][20,15][10,10]][[11,11][11,12][12,12][11,11]]]] 
(two polygons, one just exterior, one with an exterior and an interior)

Also looking at OpenLayer's svn: 
http://svn.openlayers.org/trunk/openlayers/lib/OpenLayers/Geometry/

there is a geometry object model, and I think it'd make sense to just 
dump in to something like that.

I'm also +1 on rolling in geometryType and spatialCoordinates in to one.
