I'm interested in joining the team. I looked at the Kaggle contests and I agree that the best choice would be Solar Energy Prediction, but I wouldn't discount the Phone accelerometer contest. I think its a good fit for the CLA and and interesting application. The forum posts for that contest seem to indicate the sponsors are willing to judge a 'clean' (no leakage) version of the contest.
