I think tolerance for delays on the web is actually much lower than
that -- even a full second probably drives many users away. That's
why Tor has a much harder problem.

In Email, however, no one really knows their latency -- it is rare
that someone actually is aware that a message has just been sent. I
routinely have SMSes take seconds to go through and yet I use

(Arguably one could let people tune the number of hops they pick,
trading latency for security, but experience says that way lies
horror. "There should be one mode, and it should be secure.")
