Hi,

Right.

About this specific example, I've tested VoIP between two Tor hidden
services (which means the end-to-end connection has twice as many hops
than "normal" Tor), both clients sitting behind poor DSL connections;
it results in a constant ~1s lag and no noticeable throughput problem.
Regarding subjective user experience, I would not say mine was
"severely degraded". As a matter of fact this configuration transforms
conversation a bit; it is slightly slowed down, mostly because you
need to wait 1s to be sure the person you're talking with has finished
his/her sentence before you jump to the microphone to speak yourself.
I will go as far as saying this tiny slow-down can indeed often make
the conversation greater and more dense in a certain sense, because
every part of it has had more "empty" time to mature and is thus more
thoughtful.
Bye,
