Coming from someone who has built a planning poker application in the past for use internally, can I suggest you guys provide a planning poker section to TP? If I remember correctly, it took me all of 2 days to build our basic internal one. Being able to play and point at already built stories in TP would be fantastic and would put TP at the top of the agile tools considering no one else is doing that (only a couple planning poker apps exist, and they aren't part of a ADL tool.)
