Are there any plans to expand the apps reach beyond Australia, or is there any alternative for the US?
There's also an open source project called Ohana that provides an open directory for community resources and services as well as API for people to deploy this sort of idea in their own community. http://ohanapi.org
We are looking into including additional (Australian) data sources in the future (for instance, there are some open data sets which various government agencies make available that we'd like to include).
