the traffic is encrypted in layers, your tor client "picks" the tor server,
and encrypts the traffic. Every server can decrypt his layer..
the problems are:
- what if someone owns many servers and can "see" the clients complete
- unencrypted traffic could be sniffed/alterd by the exit node, both
happens _at_ _this_ moment.
- global observer, maybe somone is able to see the complete network, if, he
is maybe able to make some cool attack.
