Hi Carol,
sanimap.NET was originally rented by me in 2007 because we (the GTZ/GIZ-ecosan team / SuSanA secretariat) had brainstormed about mapping toilets. With the formation of the SuSanA, the Japan Water Forum volunteered to work on a water/sanitation map, so I sold them sanimap.net. The result, however, isn't quite what I expected as the map has some conceptual issues, mainly the programming is too focused on the Japanese market (~ "look, we are mapping something") and also too much about water - whereas most sustainable sanitation approaches imo don't focus on water but on excreta / sludge management and much more. Also, these issues haven't been fixed since the launch, so to me it's just another one of those quick shots without any sustainability.
So when I saw that sanimap.COM is also available, I booked that one and have since routed it to another page due to the lack of time and clear focus on what I really want to map. Functioning toilets? Broken toilets? Open defecation spots? Or all of them?
And then of course I also don't want to reinvent the wheel and have thought about using an existing mapping solution like Ushahidi (or Crowdmap.com, which is the hosted version of Ushahidi). The main reason why I haven't continued working on this project though is that I'd like to see first what we can do with such mapping data and why it could matter. Maybe serve as indicators for devaid agencies, but I also believe that sanitation as such is a global problem and that it shouldn't be limited to developing countries only (even if that's where the money/funding is for such an approach).
So a Sanitation Hackathon would be interesting if it could also target the US or Europe where sludge management are still open questions. I am open to anything though and would love to find a way of combining my two favorite subjects sanitation and mobile apps.
Good part about Ushahidi is that there's an existing app for it on Android and iOS, so it's not like FLOW or so. But I am also open to more software solutions if there's a ready made solution that just needs to be adjusted.

EDIT:
Here's a reply I've meanwhile received from the fine folks at the WorldBank:
"To learn about the hackathon just follow
#sanhack or
#toilethacker. There will soon be a website as well. You might also want to subscribe to blogs.worldbank.org/water."
Great!
