If the Greek wiretapping case, switches were backdoored, so Skype
calls wouldn't be intercepted, as they are encrypted end-to-end
(discounting special cases where Skype struck a wiretapping deal with
some government — was it Pakistan?).

So there is no difference from Tor?

I see, so is that an optional feature that can be turned on by a MIX
router operator once served by a surveillance order? It seems to me
that it's an advantage over Tor, where relay operators can be served
with an order and some Tor patches that they wouldn't be able to turn
down to to the absence of a similar feature in Tor. Revocable
Anonymity seems to be designed to provide the minimum necessary
information to law enforcement.
