Please do not delete these (go ahead and put them in a DEAD directory
if you would like, though). I intend on revisiting them as soon as I
finish up with more immediate Tor tasks and lower hanging fruit. I
still believe the barriers are fundamentally engineering problems
rather than theoretical problems, but I do agree the proposals need a
rewrite to do a more clear job of enumerating and organizing the
anonymity considerations so that they are easier to grok. The prose in
115 can get a bit thick..

(And to put into perspective any fears that the anonymity issues of
two hop paths are too hairy to ever try to solve, I contend that
anonymity under Firefox is a far more fearsome beast ;)
