* What we're going to accomplish
- User freedom
- Safety for everyone
- Networked programming like y'all have never seen
- Take over the web!

* COMMENT Social vision: Spritely's bigger picture
- Social agency: MOAD2 demo
- Secure computing
- Networked and p2p by default
* Language vision: Scheme / Guile
#+REVEAL_HTML: 
** Lisp is clay
* Goblins: distributed, cooperative, transactional programming
#+REVEAL_HTML: 
** Distributed security you can understand
- If you don't have it, you can't use it
- It's just argument passing!
** Lambda: the Ultimate Security Model
