image Okay – while not exactly where I wanted to be, I now see that I’m able to easily display a KML feed in Bing Maps (the artist formerly known as Microsoft Virtual Earth) by appending a “mapurl” parameter to maps.bing.com, and then feed it in the URL to your KML file.  Like

http://bing.com/maps?mapurl=[your_kml]

For example, if you click through on the link above, you’ll see the KML file that I generated from my Flickr cross-country set, then superimposed on Bing Maps, with a nicely-formatted sidebar containing all of the other various metadata stored in the KML file.

I’ve still not been able to get their other sample to work, probably due to some sort of mime-type issue, but the above is a pretty nice feature.
