I've got northing and easting in lat long for 4 points and would like to convert these coords
to web mercator auxilary sphere and show on map as a polygon using flex api.  Do I need to create and publish a geometry service to
do a projection and then read the geometry back? -- This will need to be done repeatly in an automated fashionand I was hoping to not have to create new gis layer each time the calculation was performed
