Legend thumbnails from Javascript/REST API

Idea created by alderian72 on Jun 23, 2010
    Basically, I'm trying to build a layerlist control, much as in ArcMap, for the Javascript API. So far I have a dijit.Tree loading the layer list correctly and applying the correct heirarchy. I've located the scale dependancies information in the REST response for a layer from a map service. The only thing left is the ability to get a swatch/thumbnail of the symbology of a layer to display next to it. The SOAP interface implements this, so please can you also get the REST interface to allow the same functionality?
