    - For Rucio: Have better (and dynamic) distances in Rucio
  - (2) Inefficiencies in Rucio (and FTS)
    - See talk by Radu at FTS workshop in March
    - e.g. Why does Rucio/FTS use source X, while site X is very busy, why doesn't it chose source Y

    - More details next week
    - Martin will create issue to collect inefficiences
  - (3) Writing a control framework
