The demo I set up is here: http://bit.ly/open311sav
The City at this point seems as though it may already have its eyes on an enterprise vendor for the official 311 system reporting –– despite having mentioned it as an area we could help with earlier.
That said, the civic use-cases for this setup are numerous. The first that comes to mind is mobile users (pedestrians and cyclists) snapping photos and creating geolocated reports of dangerous intersections/crosswalks/sidewalks across the City, an issue that has repeatedly been raised by the Bicycle Campaign and others in the community.
We would just configure the setup a tad differerently to tailor it for that use-case.
