hi Alex,
You can find an example of a directly displayed GeoRSS layer at
http://www.ekoplan.org/wikimap/demo20. As you can see, I used a php-proxy to
get the georss-xml. Most likely that is your problem (the proxy). You can
find info on setting up a cgi-proxy at openlayers.org, or you can use the
php-proxy I use for wikimap for testing. You can find the sourcecode of
wikimap through http://wikimap.sf.net.
