I did opsdir review for document: draft-ietf-lmap-use-cases-04.txt Seems to be in good shape. One might want to say something about possibly overloading/congesting networks if too many measurements are taken at the same time or if tests/measurements are being done while the user/consumer/customer is trying to do real/useful work. At the other hand, that might also be described in standards documents that will most probably follow this use case document. Bert Wijnen
