It's interesting to me how many people are looking at the CoDeL piece of Preseem first - their original vision (and what I still think is the most interesting) is the direct TCP monitoring they do to try to figure out which APs have issues, which customers have issues, and what the root causes of those issues are. The CoDeL piece was just a cherry on top.
The CoDeL piece isn't very hard (if you're not worried about scaling it very far) but the monitoring and diagnostic tools they have are, I think, fantastic. I've never heard anyone not rave about them, and I know tons of people using them.
