Point layer from JSON webservice

All,

Similar to the new CSVLayer, I'd like to create a layer from a JSON webservice (has lat/lon for points). What are my options? GraphicsLayer? FeatureLayer?

Thanks,
Glen

Yes (both). Or a custom layer that extends either of those.
Using a FeatureLayer and it's feature collection is probably one of the first options you should look into. There's a sample for that:
http://resources.arcgis.com/en/help/flex-api/samples/index.html#/Time_rendered_5K_run_gpx/01nq0000002r000000/
That specific sample also deals with time-awareness, but if you simplify it and parse your json instead of gpx, you should be able to get your json point data onto the map.
