An interesting take on peer-to-peer vs. central server-based architecture for Chandler.
I would be more than delighted to see Chandler mature into if not an Outlook-killer, then at least a worthy replacement (or maybe continuation) of ECCO.
Whatever milestones are available for public review right now are not even early-adopter stuff, though.
On an unrelated (albeit still free note), if you’re looking for something to replace MS Project with — give Open Workbench a try. It is well worth it.
