I'd like to see the entire photosynth.net site take a turn for the realtime. What I mean is that it is interesting to have the 'Recently Synthed' feed available here: http://photosynth.net/Explore.aspx?filter=DateDesc/ but I would love to be able to see new synths bubble up and animate the others downstream, rather than needing to manually refresh the page. If we can use AJAX to make Windows Live Messenger toolbars, Seadragon.com progress bars, etc. then surely I'm not asking too much here, am I?
What is more, I would love to see geotagged synths bubble up to a Silverlight Map control as they are geotagged. I'm imagining a cross between this twitter map ( http://earthware.cloudapp.net/demos/sltwittermap.aspx ) and the Bing Maps World Tour except that the number of geotagged synths is so small that you could manage to report each one, rather than just one every ten seconds like the twitter map does. Browsing geotagged synths by month à la BMWT would seal the deal.
