I hung out in the absolutely packed security devroom the first day, superbly organized by Martin Paljak from OpenSC. Lots of interesting and insightful talks, and met people that I'd previously only interacted with online.
Nikos and I both gave talks about using PKCS#11 as glue to give a better crypto user experience no matter which crypto library an application uses. There was a lot of great discussion, ideas and participation. I'm looking forward to working more folks on this stuff.
