Sndwa1, you're right that that is part of the original concept and also right that this feature is not yet implemented for us (the public users of Photosynth). There are definitely a lot of people eager to see this happen.
I put together all the references to that idea that I could find last year on this page: http://getsatisfaction.com/livelabs/topics/linking_synths .
Any word from any of the Photosynth team would be most appreciated as far as current progress, but I would point out that in that last link Blaise is quoted as saying "we'll mostly be prioritizing community features over fancier visuals... my-photos-in-context [is] high on the list, though." and DariusMonsef mentioning on March 5 in the first post here that the team is currently redesigning photosynth.net.
