[OSM-dev] Displaying snapshots of BING imagery with current OSM data and an overlaying grid

Pardon the lengthy topic but it details exactly what I am looking for.
I created the Mapping Botswana project and in order to get a fairly
hesitant population to contribute I'm thinking of new ways of outreach.
A thread on Facebook (with me as Mapping Botswana) managed to get a
local to point out several key amenities in the small town of Khawa in
the Kgalagadi district, part of the Kalahari desert. Here is the thread
What I did was to screenshot from the iD editor the area, split into 4
images with adequate zoom for details and then creating a grid using
Paint.Net (decent enough image editor, freeware) before posting it. Now
doing this by hand for all 700-ish locations in Botswana seems a fairly
hard task so I'm wondering about ways to automate this somewhat. I have
already created Trello-tasks for each of these locations, for example
this is the Khawa one: https://trello.com/c/WGcTEDRQ
Why, you ask, don't you just point them to the very easy to use
iD-editor! Because, I answer, it is an extra step most people are
unwilling to do simply to just say "yeah that is the clinic and that is
the supermarket". Hopefully some users will go down this route but the
majority probably will not.
So my intention is to create an interactive version of this, where I
mark out a boundary box and then retrieve for it the Bing imagery
alongside the OSM data, exactly like iD does currently. Overlay the
image with a grid and then either allow someone (maybe using Facebook or
Twitter login - not sure about that) to submit an observation.
For example click on E6 and then type "this is the Mojhgawe Clinic" or
simply allowing them to add a point on the map and select from presets
(school, shop, clinic, bar, petrol station, other) and add it to a queue
that would then submit to OSM as a seperate MappingBotswana user or
likewise, after manual glancing at it.
So the question is, what current tools do we have that can support this
or even supplant it? Am I barking up a tree when I should be digging a
find how to do the bing+osm overlay in the iD code or someone can point
to the exact spot.
