Does anyone know of a Kanban style solution that might work well with GroupWise? I have looked at Trello but am unsure on whether I want to use a hosted service or a server I control.

I currently use TaskLists for some of my Projectect Management process. I am unsure whether I can share or send a TaskList item to someone else and still see the progress.

Anyone have any ideas on Task/Project style management that I can integrate into my GroupWise system that might be shareable with other staff members? Is this something I should be looking at Vibe/Teaming as a solution instead?
