You can release the concept and implementation as Open Source, maybe to the guys over at iHub/Ushahidi. They can adapt and find a way to better utilise the solution .
Why not deploy it commercially if it works, given there is a problem case1. I have more relevant (in my field) work than I am possibly able to cope with, this would just be but a distraction.2.

In its current form, it's of limited value.
