Reducing relays = reducing anonymity ? Tortunnel.

[Attac Heidenheim]

Hi everybody,
I just tried a little tool called "Tortunnel" which allows a user to
"tunnel" Tor via Privoxy/Polipo to any selected exitnode. Just one hop
instead of three relays.
Of course, if the exitnode ist evil, you're lost, but it really speeds
up the whole thing on the other hand.

My questions: 
Does anybody use tortunnel ?
Is tortunnel evil since it maybe hacks Tor-cirucits to reduce the number
of relays ?
Where is the security/anonymity reduction since tortunnel also uses
Tor ?
Can Tor itself reduce the number of relays (like tortunnel) ?

Greetings,
Niklas
