[Ndn-interest] NDN protocol principles: no privacy?

Hi Mark,

I'm a huge fan of privacy and a lot of my research privacy-related.
But, I can't define "privacy". I wonder if anyone can do it precisely 
and succinctly?
Might be because it's an amorphous and fluid notion.

Perhaps if NDN folks were to include *privacy* as one of their guiding 
it'd be like a stereotypical beauty pageant contestant who,
when asked about her (or his?) ideals, comes up with something
like: "Peace on Earth"?

On a less serious note, whenever I see things like codified "principles"
(a notion similar to "commandments"), I can't help but think of a new 
or a new cult being started.
