What kind of tracker do you want? You could start a Redmine/Bugzilla server, or you could write one-word "to-do's" on a whiteboard. There's a lot of work to be done, and one mechanism will not solve all your needs.

For something in the middle, I've found that a shared Google spreadsheet with status, priority, due date, title, and description columns gets the job done with near-zero overhead. Too much effort is wasted on learning/paying for/managing more complex todo lists.

A simple spreadsheet can also be useful to individuals. On that note, do either or both of you have a tool you like for individual use?
