Re the above from George, and some talk I see about
obfs versions, am I right that obfsproxy is not yet a general
pluggable transport tool? As in a library and/or standalone
proxy that two endpoints put in front of themselves,
choose from a menu of (or negotiate) obfus and say
go in a nearly automatic fashion?
A C/python library interface would be interesting, as
would deciding what the standalone proxy might be
among socks5, transparent firewall redirection, tun
interface, etc.
In addition to DNS, people have written HTTP, IRC,
ICMP, raw IP, etc tunneling tools in the past.
