I put up a little demo.
This version will only reverse geocode streets that are addressable, meaning you need to click on streets that have actual buildings on them.
Most highways have no addresses so don't be surprised if you click on an interstate and get no resuts. I also have the search distance set very low and it will only return a range of addresses, it won't guess the exact number yet.
The demo is querying the database on my home machine which has very limited power and bandwidth so it may be up and down.
