I will contact a couple of people via email that are interested in encryption support within PNA to see if they can prepare something for discussion in a future meeting, but that would not be ready for tomorrow's meeting.
As usual, please send mail to
p4-...@lists.p4.org, or to Mario Baldi or I personally, if you have any topics to present or discuss that you would like to have in the P4.org architecture work group.
