I saw this little tool on the 10K apart website: http://10k.aneventapart.com/Entry/303. And I have been using this little tool til my machine crashed, since everything was stored locally, then I gave up on it. But I saw another interesting app from the Taskboard developer Bartek Szopka.
Read this page for more information why he built the taskboard application: https://github.com/CognifideLabs/taskboard/wiki
