We got diverted from this mission during the last 18 months, but we still believe in it, and it's still part of the plans. It also fits in with the plans of our close cousins in Bing, the "Read/Write World". Blaise Aguera y Arcas who runs the Read/Write world and I are on the same page that we are working towards all geomedia (maps, streetside, photos, panos, synths, geotagged videos, ...) being "matchable" in the Read/Write world, and allowing people to collaboratively or serendipitously build immersive experiences of the places they love. I'm looking forward to getting back to this core goal.
If you have opinions about how this should work in practice, we'd love to hear them.
