Neat real-time collaborative task list manager.

Kinda cool looking task manager/note taker for Mac.
Gamatam Tasks
Gamatam Tasks tracks tasks between Worpress users, allowing users to edit the description, change the task status, change the priority and assign the task to a different user. It is not as comprehensive as most issue trackers (no work flow etc) by design, I found a lot of clients looking for something more useful than a spreadsheet or todo list, but not as complicated to use as bugzilla, trac et al.
TeuxDeux
Interesting twist on a todo list manager. Splits tasks horizontally by day, includes a “someday” section.
