I'll start off, tiny team spread apart geographically. We use Redmine as central hub for tracking progress, planning, wiki and forum for discussion and documentation. Google docs a bit for architecture and general info. IRC as official meeting room. Subversion for code repo, Redmine also as svn's browser. Project broken in to several primary chunks, and each person is fully in charge of one or two pieces. Design and Develop on our own with a interface between the parts.
