The vision is described in Country Wise List of Users in ODK Forum.
The minimum viable product for me would be a map at a forum.getodk.org/map that mapped a single "Home" location for every user. I'd like this because then it's easy for folks in a particular locale to find each other and connect. And if that goes well, I'd love to add a layer for folks to identify where they have projects (e.g., atlas.openmrs.org). Does that give you the detail you need?
