visualizing geoRSS on a globe

What are my opti开发者_JAVA百科ons if I'd like to display GeoRSS data on a globe like the one found here.

Using Openlayers, http://openlayers.org/dev/examples/georss.html

or google maps api, http://googlemapsapi.blogspot.com/2007/03/kml-and-georss-support-added-to-google.html

or Yahoo Maps : developer dot yahoo dot com slash maps slash georss (I have a two link limit)
