Should we try to organize some public chat about web caching at PETs or
HotPETs this summer? 

By that I mean, a discussion with anonymity researchers on security and
anonymity concerns around making tools like Yawning's CFC a long-term
solution to the CloudFlare problem? 

Aside from our not knowing if CloudFlare will become more accommodating,
a trustworthy web cache would enable more serious efforts towards
alpha-mixing, either in Tor itself, or with mixnets on the side of Tor.
And archival tools make the web better in numerous ways, like by making
it harder to removing anything. 

There are interesting problems in this space like :  Big scary adversary
issues.  Archiving TLS sessions along with HTML transformations so that
subsequent clients can verify the original site's certificate.  How best
to one distribute the cache.
