Perhaps this seems like a request for the Bing Maps team, but I'd like to make it simple for everyone to embed a map of synths and panos on Photosynth.net
I copied the address for a few simple map pages and pasted them into some iframes on a WordPress blog and they function okay, although they are quite crowded from an interface perspective when viewed at such a low resolution. http://notes.natelawrence.net/synthymaptests/
If you ever do officially offer embed code for your maps, I think that the Photosynth header could be dispensed with and the search box and zoom/rotation controls brought inline with the Photosynth logo.
The tray of thumbnails along the lower edge of the map view should probably adapt to different scales as well.
