Member Tasks - Possible?

Is it possible to create member tasks?

In essence like a to-do list for all members, where they can login and see the list, marking off once things have been done.

I'd be able to see who's completed what at lower (phil did x) and higher level (x% completed section y).

I am not seeing any plugins at the moment for this but would love to hear people's thoughts.

Thanks,
George
