a) This is ancient history revisited, with a little hype and horse flop
sprinkled around for effect. The issues in question are well known,
well documented, over discussed by people who don't quite understand
them, and already addressed to a large extent by people who do. Roger's
"heartburn" simply doesn't exist.
b) No it doesn't. Tor has several built in defenses that address
owners of multiple nodes. Not building circuits that use two nodes in
the same /16 IP block for example. Rotating entry points among a small
pool of "trusted" nodes would be another. The network being inherently
self correcting with respect to nodes that lie about throughput and
uptime, yet another.
c) Before claiming something is "broken" you should at least be
vaguely familiar with what it's suppose to "fix". Please read sections
3.1 and 7 of this document:
