The "Recommendations on Anonymization Processes for Source IP Addresses Submitted for Future Analysis" document had moved the caucus for discussion. One of its proposed anonymization schemes was Cryptopan, from the work of Xu, Fan, Ammar and Moon from Georgia Tech. For folks who are interested, an update about cryptopan: we pulled our implementation out into a library, at <https://ant.isi.edu/software/cryptopANT/index.html>. GaTech has an implementation as well. Ours was done independently from theirs (theirs was not released when we started), but both follow their paper. We identified some small implementation differences that prevent interoperability, but it would be fairly easy to align them. I think that points to the clarity of the original paper. Details are at <https://ant.isi.edu/software/cryptopANT/index.html>. -John Heidemann
