The most valuable things in the talk were linkerd and BGP (especially configuration of Zebra and linkerd), unfortunately both were only glossed over briefly.
Has linkerd been ported over to SmartOS? (So far I haven't found anything saying one way or the other.)
For your next talks, please describe as many failure scenarios as you can think of, and what happens at the OS / application / network level. The more concrete failure examples you can provide, the better.
The why's are clear. The mechanisms are not.
