- Zooko's triangle with examples of systems that have "two of three".
- Namecoin's solution with a brief reference to the Bitcoin blockchain but not too much. (There's a workshop on Bitcoin by Coinfinity and a Bitcoin booth, although I don't think they'll dive too deep into the technical details.)
- .bit domains plus id/ for key exchange as two important use cases.
- Name management with name_new, name_firstupdate, name_update.
- How to set up your site to use .bit, and mention that one can also use NameID to handle user log-ins instead of a user/password database.
I think that there may be quite some interesting "targets" in the audience. A group in Graz is working on a "tracking resistant" browser (Privacy Machine), there is a local Bitcoin start-up (Coinfinity) and a group is even trying to redesign the Enigmail user interface via thesis proposals at a university here.
