@SteveBellovin - Note that running the tool isn't required. The chairs are trying to be helpful and transparent. There are A LOT of submissions and there were lot of questions about administrative rejections in Cycle 1.
I encourage you to read Elissa and Ben's between-cycle transparency report: https://docs.google.com/document/d/e/2PACX-1vSnHpeTFReelMZ124SzmgObXrHDN_B-UgxhOaE2RKfnfHn_qWuobI7kPg4TKBMhhZy_qxYtggCo7vjK/pub
For what it's worth, the Python program is hosted on the co-chair's research group's website at CISPA. If this is something USENIX wants to use going forward, we will definitely host it directly.
