"We are working on documenting these security tradeoffs in detail in our whitepaper (and any attempt I make to describe them here will be less accurate and thereby dangerous ;P)."

Maybe a whitelist of nodes themselves? (mostly in jest there)

I suppose an agency with funding who can endlessly sockpuppet could gain a substantial portion of network nodes, but if they're unable to censor more than per-random-packet, a surveillance goal seems more likely. While this may not meet conventional definition of 'censorship', I wonder of the chilling effect. I suppose any such move toward a censorship-free network should expect surveillance. c'est la vie.

Thank you for taking time to answer my question.
