Software for Community Organisations

I was having a look around spreadfirefox.com – the new, beta, community Mozilla promotion site when I came across this
http://www.civicspacelabs.org/.

It is described as " a grassroots organizing platform that empowers collective action inside communities and cohesively connects remote groups of supporters" and from the looks of things is basically a bunch of organising tools built on top of a CMS. It is aimed at community and campaigning groups, and its intended use is distributed organising, and looks like it might be useful for some projects we (might) work with; I was thinking specifically of the ERN.
